Description

Issue: HTTPSCallable's callWithObject:completion does not invoke the completion block on the main thread.

Regression: This appears to be a regression from #14085.

Reproducing the issue

1. Create an HTTPSCallable function.
2. Invoke it with callWithObject:completion

Expected results: observe that the completion block is called on the main thread.
Actual results: the completion block is called on a background thread.
