Perform moban synchronization after each push and each PR.

[chfw]

No longer, a forgotten moban synchronzation cause issues.

For short term contributors: we understand that getting your commits well
defined like we require is a hard task and takes some learning. If you
look to help without wanting to contribute long term there's no need
for you to learn this. Just drop us a message and we'll take care of brushing
up your stuff for merge!

Checklist

• I read the commit guidelines and I've followed
  them.
• I ran coala over my code locally. (All commits have to pass
  individually. It is not sufficient to have "fixup commits" on your PR,
  our bot will still report the issues for the previous commit.) You will
  likely receive a lot of bot comments and build failures if coala does not
  pass on every single commit!

After you submit your pull request, DO NOT click the 'Update Branch' button.
When asked for a rebase, consult coala.io/rebase
instead.

Please consider helping us by reviewing other peoples pull requests as well:

• pick up any PR at https://coala.io/review
• review it (check https://coala.io/reviewing for more info)
• if you are sure that it needs work, use corobo mark wip <URL> to get it out
  of the review queue.

The more you review, the more your score will grow at coala.io and we will
review your PRs faster!

As you can see, the branch contained some updates that were performed by this github action.

Hence, looking at the number of developers in coala project, this github action would save a lot of developer time, not to worry about moban synchronization.

@chfw Actually it's not that simple, coala has some commit checks which can cause the build to fail. Also, we don't support python 3.7 yet so the sync has some problems? I guess the changes are due to upstream templates. For some reason if you check the pinned version of moban here it doesn't give any new changes during sync. But upgrading it will give these changes.

This will need another look as the current moban version does not add the python version 3.7 (which we don't support yet). I'm not exactly sure what the problem is or from which template this gets added.
