[EPGSearch] GREEN Add timer hint displayed when search list is initially empty

[prl]

[EPGSearch]

If the EPG Search is started displaying an empty list, the GREEN button hint shows "Add timer", even though Add timer works on the current selection. If GREEN is pressed when the search list is empty, there is no user feedback (like the "unhandled key" popup).

Replication steps

On a T4 change service to HDMI IN (no HDMI input is necessary). Press YELLOW for EPG Search. An empty search list is displayed, but the GREEN button hint shows "Add timer". If GREEN is pressed, nothing happens.
