Autotimer "description" search fails if no service restrictions

[prl]

If an AutoTimer with "description" Search type is created with no service or bouquet restrictions, the timer won't match events that contain the description text.

Replication steps

In any convenient way, create an AutoTimer with "description" Search type and a "Match title" string that is known to match at least one instance of a program. Set its Restrict to specific bouquets setting to a bouquet that contains the program (e.g. Terrestrial TV LCN).

Verify that the AutoTimer matches programs as expected using MENU>Preview in the AutoTimer list screen.

Remove the restriction in Restrict to specific bouquets.

MENU>Preview now matches no programs.
