Add null check in FLETextInputPlugin (flutter/engine#8538)

Browse Source 
Adds a guard on `_activeClientID` in `insertNewline:`. The conditional
around the `insertText:replacementRange:` call already catches this, but
we then unconditionally pack `_activeClientID` into an `NSArray`, which
disallows nil.
