was [requested in the
forum](https://forum.magicmirror.builders/topic/17519/updatenotification).
- added possibility to exclude MagicMirror Repo and renamed it from
`default` to `MagicMirror`
- improved getting `behind` in case a hard `git fetch` was already done
- removed test "excludes repo if refs don't match regex" because of
above improvement this case is obsolete
- improved `git fetch --dry-run` with `-n` option to exclude tags (noise
reduction)
This PR resolves a small bug in the updatenotification module if a local
git repo is ahead of the remote (for example I have made local commits
for my personal needs).
Currently, if `git status -sb` reports a status like: `##
master...origin/master [ahead 2]` then updatenotification treats this as
though it's "behind".
This PR uses a single Regex to match `git status -sb` output and uses
capture groups to extract info to populate the `gitInfo` object to avoid
needing to do string manipulation to extract this information.
