conflicts: make spacing consistent in conflict markers

The way default marker template was defined before this patch,
the spacing before dash in conflict markes was dependent on
whether changeset is a tip one or not. This is a relevant part
of template:
    '{ifeq(tags, "tip", "", "{tags} "}'
If revision is a tip revision with no other tags, this would
resolve to an empty string, but for revisions which are not tip
and don't have any other tags, this would resolve to a single
space string. In the end this causes weirdnesses like the ones
you can see in the affected tests.

This is a not a big deal, but double spacing may be visually
less pleasant.

Please note that test changes where commit hashes change are
the result of marking files as resolved without removing markers.
