Fix mounted checks (#1043)

Fixes in preparation for https://dart-review.googlesource.com/c/sdk/+/330561. The change referenced above tightens the `use_build_context_synchronously` lint to ensure that `mounted` is checked on the appropriate `BuildContext` or `State`. This change fixes up the gallery in preparation of this new enforcement.
