Subject: [PATCH] contrib: rerere-train overwrites existing resolutions

When running rerere-train, the user is explicitly asking the training to
occur based on the current merge commit. However, if the current cache
has a resolution for the same conflict (even if out of date or wrong),
rerere-train does not currently update the rr-cache. Now, forget
existing resolutions before training so that training is always
reflective of the trained data.
