Fix combining continue/next-up for new episode premieres (#381)

Better handling for combining continue/next-up by considering the
premiere date of the episode. So episodes will use the previously
watched one's last played date or the episode's premiere date, whichever
is newer.

This means when a new season comes out or the show returns from a break,
the new episodes will show earlier in the list like the next up rows
shows when not combined.

Fixes #377
