There were several issues here. Key uploads in general failed, because
the await caused a Future<dynamic> to be returned, which failed type
checking.
But also we never unset our future, which was used for the online key
backup uploads, which meant we would very quickly stop uploading any
keys at all.
BREAKING CHANGE: This changes the runInRoot method to not return a
future. As a user, if you need the result of an async computation passed
to runInRoot, please await it directly. Also the KeyVerification start
and a few call methods now return a future.
