list-objects: move tag processing into its own function

pks-t · gitster · commit 628d81be6c00 · 2021-04-10T23:03:20.000-07:00
Move processing of tags into its own function to make the logic easier
to extend when we're going to implement filtering for tags. No change in
behaviour is expected from this commit.
