rCOMM34785f4641f4: [keyserver] Introduce `isCookieMissingSignedIdentityKeysBlob`

Summary

Checks if there's an existing row in cookies table with id=cookieID with a NULL signed_identity_keys column.

We're going to use this check in handleInitialClientSocketMessage to determine whether or not to send SIGNED_IDENTITY_KEYS_BLOB request to client from keyserver.

Depends on D7049

Test Plan

Called function from handleInitialClientSocketMessage:

if (viewer.cookieID) {
  isCookieMissingSignedIdentityKeysBlob(viewer.cookieID);
}

and set breakpoint within isCookieMissingSignedIdentityKeysBlob to check whether queryResult was as expected when signed_identity_keys was NULL and a valid stringified SignedIdentityKeysBlob:

I think this diff would be easier to review if you included this new function's usage in the same diff

keyserver/src/session/cookies.js
820–826 ↗	(On Diff #23655)	I'm not a fan of `if () return true else return false` constructions. This sort of construction can always be rewritten: return !!( queryResult.length === 1 && queryResult[0].signed_identity_keys === null ); Separately, I might consider either making the comparison `> 0` or factoring out the check that there aren't 2 or more results into an `invariant`

820–826 ↗	(On Diff #23655)	Personally prefer being explicit instead of the casting trick... but I'll update this diff.

820–826 ↗	(On Diff #23655)	Separately, I might consider either making the comparison > 0 or factoring out the check that there aren't 2 or more results into an invariant It's totally impossible for more than one row to have the same `id` so I think it's fine to check `=== 1` return !!( queryResult.length === 1 && queryResult[0].signed_identity_keys === null ); Shouldn't this just be return ( queryResult.length === 1 && queryResult[0].signed_identity_keys === null );
