[lib] create session with peer only when it is missing

Summary:
ENG-6982.

ENG-8527.

We definitely shouldn't attempt to create a session when sending a message using Tunnelbroker fails.
According to Olm docs encrypt could throw only two errors:

• NOT_ENOUGH_RANDOM
• OUTPUT_BUFFER_TOO_SMALL

and attempting to create a session for those two is not to attempt new session creation, the only case is when the session is missing.

The alternative is to not update the code because peerOlmSessionsCreator is idempotent but we can avoid additional worker/CommCoreModule calls.

Depends on D13025

Test Plan: Test that when session is missing, it is created.
