t3310: stop checking for reference existence via `test -f`

One of the tests in t3310 exercises whether the special references `NOTES_MERGE_PARTIAL` and `NOTES_MERGE_REF` exist as expected when the notes subsystem runs into a merge conflict. This is done by checking on-disk data structures directly though instead of asking the reference backend. Refactor the test to use git-rev-parse(1) instead.
