Firebase 6.7.0 crash hard_assert_apple.mm line 34

[Banck]

• Xcode version: 10.3.
• Firebase SDK version: 6.7.0
• Firebase Component: Firestore, Messaging
• Component version:
  Core-6.2.1
  Firestore-1.4.4

I've updated to firebase 6.7.0 from 6.6.0 due another crash, which was fixed in #3623 .
But in 6.7.0 there is a new crash from fabric reporting:

Fatal Exception: NSInternalInconsistencyException
FIRESTORE INTERNAL ASSERTION FAILED: Expected to be called by the executor associated with this queue (expected executor: 'com.google.firebase.firestore', actual executor: 'com.apple.main-thread') (expected executor_->IsCurrentExecutor())

@Banck Thanks for the report. This looks like a duplicate of #3661 that was fixed in a Firestore patch update yesterday. Please run pod update to get the FirebaseFirestore 1.4.5 pod.
