FIX: mythfrontend crashes bring up the guide when no channels are defined

Reproduce by: 1- remove all channels 2- From main menu: Manage Recordings -> Schedule Recordings -> Program Guide

I suspect this also affects the guide from LiveTV (but I did not verify.)

The fix I did is below:

(In [12960]) Don't try to fill in the program infos on the EPG if we don't have any channels in the database.

Fixes segfault that would occur if you entered the EPG with an empty channel table.

Closes #3102.
