pull-requests: fix way how pull-request calculates common ancestors.

- fixes  #5561
- added new preview for size (commits/files) of PRs before opening, this is now based on the special logic that calculates common ancestor and has access to preview diff
- store common ancestor in DB so updates of pull-requests are consistent
