t5520: make test_pull_autostash() accept expect_parent_num

Denton-L · gitster · commit f8a178580719 · 2020-04-10T09:28:02.000-07:00
Before, test_pull_autostash() was hardcoded to run
`test_cmp_rev HEAD^ copy` to test that a rebase happened. However, in a
future patch, we plan on testing merging as well. Make
test_pull_autostash() accept a parent number as an argument so that, in
the future, we can test if a merge happened in addition to a rebase.
