Fixes #10566. Reverts part of 3a51b83 to improve channel changes.

The first half of 3a51b83 looks like a bug (the new condition means
the following "else if" branch is never taken).  Removing it stops
guide-based channel changes from being forced onto a different tuner.

Note: this fix exposes another problem with guide-based channel
changes - you can't switch to a different tuner in the current input
group.  Fix is in progress.
