Auto merge of #8274 - Eh2406:8249-repro, r=alexcrichton
reset lockfile information between resolutions #8249 pointed out that some kind of lockfile data was leaking between calls to the resolver. @ehuss made a reproducing test case. This PR resets the `LockedMap` data structure when calling `register_previous_locks`. lets see if CI likes it. fix #8249
