Tag before pulling and rebasing

[andreasf]

Tag should tag the current commit id of the working directory before pulling and rebasing. otherwise, manually triggering a job can lead to tagging the wrong commit.

Steps to reproduce:

1. Create a pipeline that gets, tags and pushes
2. Add a commit in the source repo and trigger the pipeline
3. Increment the version resource so that another commit can be tagged
4. Manually trigger the pipeline again.

Expected behavior:

The tip commit of the source repo should get tagged again.

Actual behavior:

Out pulls the tag commit from the destination repo. Since there is no new commit in the source repo, the old tag commit ("Added tag ... for changeset ...") is now at tip, and out tags it with the new version number.
