Fixes #1390
Previously the handler for unrolling rollups assumed that the commits were ordered bor's auto merge, all roll up merges, all individual commits (in reverse order), but this is not always true. In rust-lang/rust#100356 for example, an individual commit made it in between roll up merge commits.
This simplifies the code to not make this assumption.
