Fix a few flaky tests in several products (Auth, Analytics, Storage, RTDB, Firestore)

[jonsimantov]

Fix some more tests that fail due to flakes, usually because of network instability.

Auth: Add retry in TestLinkAnonymousUserWithEmailCredential.
Analytics: Add retry to TestGetAnalyticsInstanceID, and Android retry to TestResettingGivesNewInstanceId.
Storage: Add additional timestamp logging and switch to verifying against remote timestamp, as FTL device local time is unpredictable.
Database: Switch to verifying against remote timestamp, as FTL device local time is unpredictable.
Firestore: Android tests are now timing out on FTL after 90 minutes, so bump up the FTL timeout by 30 more minutes.
