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.
