Currently we specify versions for Gitlab-Shell, Workhorse and Gitaly
using version strings, to which we prepend 'v' and assume are tags.
These changes allow branches or tags with other name formats to be
specified by prepending '=' to the version string (á la govendor).

We also simplify the process to reset to the given version (now a
branch or tag): Right now there's a check to supposedly try to avoid
fetching from the remote the version if it already exist locally. But
the previous logic already clones if the directory doesn't exist or
fetches if it does, so this check is pointless. We can safely assume the
version exists once we get to the reset stage.

Given a valid pipeline job, and a regex which wouldn't match to a jobs
trace, the stream of the trace would return the File object. This was
not the case when it matched a value, as that would have been return
from the block.

Now the `extract_coverage` method returns `nil` if no match was found.

When renaming, the argument on the projects hook API was forgotten. Now
one could successfully set it again.

The fix is a little ugly stylewise, but needed as the underlying model
still refers to it as build_events. This commit is to fix it, later we
should migrate the data to a new column. The edit on the spec file makes
sure it passes now, and will fail when we migrate the column.
