[lib] Disable keyserver session recovery when paramOverride is specified

Summary:
We currently use paramOverride in three places in the codebase:

1. UsernameSelection on native, where we call useLegacyAshoatKeyserverCall with paramOverride set to override urlPrefix for exactSearch.
2. ConnectEthereum on native, where we call useLegacyAshoatKeyserverCall with paramOverride set to override urlPrefix for both exactSearch and getSIWENonce.
3. useIsKeyserverURLValid, where we call useKeyserverCall with paramOverride set to override keyserverInfos as follows. (D10290 does something similar for useVerifyInviteLink.)

keyserverInfos: {
  [keyserverURL]: {
    urlPrefix: keyserverURL,
  },
},

In all of these cases, we're calling a keyserver before we've authenticated to it. Since keyserver session recovery functionality is only relevant when a session invalidation occurs, it's not needed in these cases.

The reason I want to disable it broadly for cases of paramOverride being set is that paramOverride can be set to override something more important, such as the cookie. We keep just a single set of waitingCalls for each keyserver... as such, you could imagine somebody setting paramOverride to an incorrect cookie, and triggering a session recovery when the cookie in Redux is actually correct.

Depends on D10950

Test Plan:

1. Test successful session invalidation in single keyserver world
   1. I prevented the Socket from rendering by adding a return null line before the other returns in KeyserverConnectionHandler. This avoided the Socket triggering session recovery.
   2. I started the iOS simulator and logged in using a test user.
   3. I opened the Redux Dev Tools
   4. I deleted the test user's cookie from the MariaDB database: DELETE FROM cookies WHERE user = 6390578 AND platform = 'ios'
   5. I sent a message as the test user
   6. I confirmed that session recovery was triggered in the Redux dev tools (and through some console logs)
   7. I repeated the process above several times to make sure it consistently worked multiple times in a single run
   8. I confirmed that the message was delivered "transparently" (without any visible issues, or evidence of session invalidation)
2. Test failed session invalidation in single keyserver world
   1. I ran through the above test, but I hacked legacy-recover-keyserver-session.js to use the wrong password so the session recovery would fail
   2. I confirmed that I was logged out, and that an alert appeared explaining that my session was invalidated
3. Test logging out during session recovery
   1. I triggered an infinite loop of session recoveries by running through the above test, but swallowing the SET_NEW_SESSION
   2. I logged out of the app
   3. I confirmed that the session recovery loop stopped, and that I was logged out successfully
