fix(orm): return soft delete query results to be consistent with normal query operation results

[pxDot]

Summary of changes

the functions of the soft-delete plugin restoreOne(), restoreMany(), hardDeleteOne() & hardDeleteMany() are using the query functions patchOne(), patchMany(), deleteOne() & deleteMany() under the hood. We should probably return the result of those operations as well so they are consistent and can be used identically to the underlying query functions.
