lib-storage: mail_storage_set_critical() - log error using user's event Fix test-storage unit test to also initialize mail_user.event so it won't crash.

lib-storage: Fix error logging after mail_storage_set_internal_error() The function doesn't actually set the last_internal_error and it also doesn't update last_error_is_internal, so calling mail_storage_get_last_internal_error() afterwards could be returning an error for some different older error. Since there's no parameter to set the internal error string, just reset last_error_is_internal=FALSE.
