Subject: CI: clean up all but the correct tag
X-Git-Tag: 1.13.901~157
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5789e8b930f42f45b72d21c3fe448f1b40fca565;p=platform%2Fupstream%2Flibinput.git

CI: clean up all but the correct tag

We should rely on the provided tag, not latest.
Move the clean stage at the end, there is no point in running it at
the beginning.
