checkout.c: use ref_exists instead of file_exist
Change checkout.c to check if a ref exists instead of checking if a loose ref
file exists when deciding if to delete an orphaned log file. Otherwise, if a
ref only exists as a packed ref without a corresponding loose ref for the
currently checked out branch, we risk that the reflog will be deleted when we
switch to a different branch.
Update the reflog tests to check for this bug.
The following reproduces the bug:
$ git init-db
$ git config core.logallrefupdates true
$ git commit -m Initial --allow-empty
[master (root-commit) bb11abe] Initial
$ git reflog master
[8561dcb master@{0}: commit (initial): Initial]
$ find .git/{refs,logs} -type f | grep master
[.git/refs/heads/master]
[.git/logs/refs/heads/master]
$ git branch foo
$ git pack-refs --all
$ find .git/{refs,logs} -type f | grep master
[.git/logs/refs/heads/master]
$ git checkout foo
$ find .git/{refs,logs} -type f | grep master
... reflog file is missing ...
$ git reflog master
... nothing ...
