WebFrontend: Fix TV->Program Search (by Channel)

Only a single channel is presented with v30. Commit 63a5a20
added extra filtering options to Channel/GetChannelInfoList.
Adjusted programsearch.qsp file to account for this.

Bug reported by user tekdoc on the Forum and thanks for testing
the fix too.
