ui-diff: Check the return value of get_sha1()
Sync with what we do everywhere else and check the return value of get_sha1() instead of calling sha1_object_info() to validate the object. Note that we later call lookup_commit_reference(), which checks that both SHA1 values refer to commits, anyway. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
