Previously, we would catch any Exception thrown by VerifyRemoteList and
perform an auto-cleanup (if specified in the options). However, we
should only perform the auto-cleanup if VerifyRemoteList detected an
issue with the uploaded files. Otherwise, an unrelated exception can
cause the database repair to be performed unnecessarily. In the case of
a connection issue, this can leave the database in a corrupted state.
This fixes#4516.
