submodule: do not pass null OID to setup_revisions
If "git pull --recurse-submodules --rebase" is invoked when the current branch and its corresponding remote-tracking branch have no merge base, a "bad object" fatal error occurs. This issue was introduced with commit a6d7eb2c7a ("pull: optionally rebase submodules (remote submodule changes only)", 2017-06-23), which also introduced this feature. This is because cmd_pull() in builtin/pull.c thus invokes submodule_touches_in_range() with a null OID as the first parameter. Ensure that this case works, and document what happens in this case.
