fix: possible crash - Githubissues

Related tasks

Fixes #10 , might also affect #34 , #39 and #51

Changes

Setting lastResult field to null when success or error message was delivered to prevent calling it more than once, which causes RuntimeException

Troubles (optional)

Saving Result in class field, waiting for BroadcastReceiver callbacks and using it in onActivityResult looks kind on unstable. Fixing it will probably lead to significant changes in the API.

Note (optional)

No breaking changes, the purpose is to evade crash, it still will not propagate second received code to Flutter
Unstable crash on second received code
Unstable crash on timeout
