Empty (i.e. uninitialized engines) could receive tombstones before being initialized. Initialization checks that the engine is empty (save for the cluster version) and thus failed. Simply don't write tombstones to uninitialized engines, which is fine since by the time the callbacks fire, at least one is initialized anyway, and besides, this mechanism is best effort. The alternatives would have been to either allow tombstones to be present on an engine that is being bootstrapped, or to give the storage the option to defer writing to the engine once it's bootstrapped. Neither seemed worth the extra work. Fixes cockroachdb#55576. Release note: None
