mocker can not replace a object/module two times

[Francisco Souza]

Mocker is unable to replace a object/module two times:

>>> import mocker
>>> m = mocker.Mocker()
>>> dt = m.replace('datetime.datetime')
>>> dt()
<mocker.Mock object at 0x859ea6c>
>>> m.result('my datetime')
>>> m.replay()
>>> from datetime import datetime
>>> datetime()
'my datetime'
>>> m.restore()
>>> from datetime import datetime
>>> datetime() # the original
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Required argument 'year' (pos 1) not found
>>> dt_new = m.replace('datetime.datetime') # replacing for the second time
>>> dt_new()
<mocker.Mock object at 0x859eecc>
>>> m.result('other datetime')
>>> m.replay()
>>> from datetime import datetime
>>> datetime()
'my datetime'
>>>

The API is being used improperly:

    def restore(self):
        """Restore changes in the environment, and return to recording mode.

    def reset(self):
        """Reset the mocker state.

        This will restore environment changes, if currently in replay
        mode, and then remove all events previously recorded.
