Reactivating Mythweb power search overrides creating invalid recording schedules

[mythtv@…]

Since commit 254d59b to mythweb, reactivating an override in mythweb on a show scheduled by a power search creates an invalid recording schedule.

The schedule created has the subtitle of the show as the search phrase, and the backend log is filled with invalid SQL statement errors

Steps to recreate:
1: Select 'Never Record' on an upcoming show on a power search in mythweb
2: Reactivate that showing

Clear the search type when creating an override or don't record for
non-manual rules. Based on a patch from david.osguthorpe.

Fixes #10580 and fixes #10650 .
