from BF-34053 it is possible to EBUSY during recovery, which the server doesn't handle well (it crashes)

The underlying cause is https://github.com/mongodb/mongo/blob/76668d15b512e334dba15f49ec0a0dc217b1f903/src/mongo/db/catalog/index_catalog_impl.cpp#L1316 where we drop+create indices that were incompletely built when recovery began.

The proposed fix is to remove all of the index entries (using truncate) rather than drop+create
