treewide: use setup_revisions_from_strvec() when we have a strvec

The previous commit introduced a wrapper to make using setup_revisions()
with a strvec easier and safer. It converted spots that were already
doing most of what the wrapper did.

Let's now convert spots where we were not setting up the
free_removed_argv_elements flag. As discussed in the previous commit,
this probably isn't fixing any bugs or leaks (since these sites wouldn't
trigger the re-shuffling of argv that causes them). This is mostly
future-proofing us against setup_revisions() becoming more aggressive
about its re-shuffling.
