fix: remove repeated calls to self._get_reason (#1513)
fix: remove repeated calls to self._get_reason (#1513)

self._get_reason is being called in \_\_init\_\_ (https://github.com/googleapis/google-api-python-client/pull/1185)  , so why not save it then?
also in the \_\_repr\_\_ function we got the reason by calling the _get_reason function right in the beginning, but was then called again.
