[EPGCache] Can't search description with Freeview/Virgin providers selected

[wedebe]

While testing OpenWebif's EPG search, I've found that searching EPG by description (using OpenWebif) returns no results.

Freesat w/ Virgin actiive returns no results, however...

With OpenTV EPG activated and channel tuned for a while, the same text-in-description search then returns the expected results.

I believe EPGCache populates shortDescription or longDescription based on activated EPG providers, and that the search is only performed on one of those fields.
