Fix AT-URI parsing in PR merge master

The parse_target_repo_info function expected 4 parts in a split AT-URI but valid AT-URIs only have 3 parts after stripping the at:// prefix. This caused all PR merges to fail with 'Invalid target repo AT-URI'. Fixed the length check from < 4 to < 3 and the rkey index from 3 to 2.
