feat: skip unnecessary updates in SessionAuth

[porcellus]

Summary of change

skip unnecessary updates in SessionAuth

Related issues

Test Plan

Added an extra test that replacates a case we've seen on a user call: running signout on context updates that have doesSessionExist === false. This used to trigger an infinite re-render loop.

Documentation changes

None, this is a small optimization that people should not rely on.
