Code restructuring during 2.20 period broke fetching tags via
"import" based transports.

* fc/fetch-with-import-fix:
fetch: fix regression with transport helpers
fetch: make the code more understandable
fetch: trivial cleanup
t5801 (remote-helpers): add test to fetch tags
t5801 (remote-helpers): cleanup refspec stuff
