This change removes workarounds that were introduced prior to landing
Dart language feature
https://github.com/dart-lang/language/issues/1274, which allows type
promotion in null safe code to account for local boolean variables.
The workarounds ensured that the code would analyze the same
regardless of whether the feature was enabled, allowing for a smoother
transition.  Now that the feature has fully landed, the workarounds
aren't needed anymore.

This time making sure to deref the native object on GC.
