[PATCH v2 28/27] tests: run tests omitted by PREPARE_FOR_MAIN_BRANCH

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Reinstate the test coverage lost due to PREPARE_FOR_MAIN_BRANCH. The
remaining impact of that prerequisite was mainly missing coverage from
submodule fetches being lost[1], e.g. impacting my in-flight
ab/retire-parse-remote. Now the prerequisite is effectively a
noop. This goes on top of [2].

I'm not removing the PREPARE_FOR_MAIN_BRANCH prerequisite to keep this
change small, instead it's now effectively a noop. It can be removed
in some later change.

The only remaining occurrences in t5526-fetch-submodules.sh can be
removed without breakage with:

    perl -pi -e 's/PREPARE_FOR_MAIN_BRANCH //g' t/t5526-fetch-submodules.sh

Which at this point leaves only the now-unused prerequisite
declaration in test-lib.sh.

The coverage in t9902-completion.sh was restored by partially
reverting[3]. After that we were left with one test in a mixed
state. It setup "master" but tested for "mai". Change it back to
"mas", pending a more complete refactoring of that test.

This change only conflicts between next..seen by clashing with Peter
Kaestle's in-flights submodule fix[4]. Fixing the resulting logic
error in t5526-fetch-submodules.sh is trivial, simply:

    - compare_refs_in_dir A origin/master B origin/master
    + compare_refs_in_dir A origin/main B origin/main

This is not a replacement for that subsequent cleanup, but seems like
a simple enough thing to have now to reinstate the missing test
coverage.

Perhaps there's some topics not in "seen" that you have in mind as
conflicting, but as noted above the conflict produced here with
in-flight in "seen" is trivial.

Seems worth having that sooner than later if Junio's willing juggle
that.
