topic: compatibility for tr.changes[b'phases'] in hg 5.3 and older

tr.changes[b'phases'] used to be a dict keyed with revnums, but now it's a list
of tuples where the first element is a range() of revnums.

In this patch, instead of properly converting the data (i.e. grouping revisions
into ranges), we just wrap every individual revnum into a 1-tuple. This is not
ideal, but good enough for the existing code below.
