rerere: recalculate conflict ID when unresolved conflict is committed
Currently when a user doesn't resolve a conflict, commits the results, and does an operation which creates another conflict, rerere will use the ID of the previously unresolved conflict for the new conflict. This is because the conflict is kept in the MERGE_RR file, which 'rerere' reads every time it is invoked. After the new conflict is solved, rerere will record the resolution with the ID of the old conflict. So in order to replay the conflict, both merges would have to be re-done, instead of just the last one, in order for rerere to be able to automatically resolve the conflict. Instead of that, assign a new conflict ID if there are still conflicts in a file and the file had conflicts at a previous step. This ID matches the conflict we actually resolved at the corresponding step. Note that there are no backwards compatibility worries here, as rerere would have failed to even normalize the conflict before this patch series.
