[PATCH v2 05/17] fetch tests: refactor in preparation for testing tag pruning

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

In a subsequent commit this function will learn to test for tag
pruning, prepare for that by making space for more variables, and
making it clear that "expected" here refers to branches.
