Homeassistant: Fixes revert issue.

[ludeeus]

Description:

The revert function of the update script for homeassistant always reverted.
Example:

Successfully installed homeassistant-0.79.2 pip-18.0
Deactivating virtualenv
Config check failed for new version, do you want to revert? [Y/n] : n
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting homeassistant==0.79.0

This PR corrects that behavior.
