test(readarr): seed profile and tag maps so empty and failure assertions can fail

The empty-response and failure tests asserted the maps were empty against a
default state that was already empty, so they passed even with the fetcher
body removed. Seeding a stale entry first makes the empty-response tests prove
the fetcher replaces rather than merges, and the failure tests prove the update
closure never runs on a non-success response.
