Consistently format package names when processing hints.

The initial packages of a hint are HintItems, whereas other packages
considered whilst processing the hint will be MigrationItems.  In
either case, the version information is irrelevant during the output
of hint processing and only displaying it for some items is confusing
and distracting.  Therefore, whilst processing a hint we always use
unversioned names.
