test: drop dead TestCliBibFetchPfsComments coverage class (refs #615)

The class drove `fetch-pfs-comments` against a MagicMock store to cover
line numbers that no longer exist — the same defect as the class removed
in 3df7a3f. A mock store asserts nothing about the fetch loop, which now
lives in walk_docket and is covered by tests/bib/test_walk_docket.py and
tests/cli/test_bib_fetch_sealed.py.
