Jesse Pretorius fe537c7a29 Fix cache update after initial apt_repository fail
If apt_repository fails to update the apt cache after updating the
configuration, retries don't register there was a change and so no
attempt is made to update the cache by the module on the second attempt.
This failure can result in a failure to install packages.

This change adds an apt module task to update the cache if the
apt_repository task registers a change. This means updating the cache
will get retried on failure and no longer fail silently.

# When updating the cache in the apt_repository

# detect a change the second attempt and therefore
# does not update the cache, resulting in a changed
# repo config, but no updated cache. To work around
# this bug we implement the change of repo config
# and the cache update as two seperate tasks.
