Peter Argany b4d5ffb804 Guard against nil bridge during teardown
Summary:
A UBN surfaced in v252 because [this assert](https://our.intern.facebook.com/intern/diffusion/FBS/browse/master/xplat/js/react-native-github/React/Modules/RCTEventEmitter.m?commit=e5d1e6375a640d0387bb7016d3becd262c22c327&lines=40) started firing, originating from `RCTAppState`.

This appears to be a race condition during RN teardown. RN receives a memory warning and attempts to forward to JS, but the bridge is already destroyed.

IMO, if the bridge is already destroyed, then there shouldn't be a need to send a memory warning to JS? This is just a hunch though, if anyone feels otherwise, please let me know :)

See the UBN task for further details.
