Core: Pass down the types from the delete mapping request to the dele…

…te by query request.

The `.percolator` type is a hidden type and therefor the types from the delete mapping request should passed down to the delete by query request, otherwise the percolator type gets ignored and the percolator queries don't get deleted from disk (only unregistered).

Closes elastic#7087
