Maxepisodes with back-to-back recordings records one too many and expires oldest

[SiliconFiend@…]

As described on the mailing list here: http://www.mythtv.org/pipermail/mythtv-users/2012-August/338829.html

Quick summary: When recording back-to-back showings that match the same schedule which has "No. of recordings to keep" set to a non-zero value, the scheduler will record one more than the available number of "slots" for the given schedule. After the extra recording is finished, the oldest recording is expired to satisfy the Max Episodes setting. Expected behavior is simply to not record the extra show and preserve the existing recorded episodes.

Version is v0.25.1-58-g1d41f74

starts recording was broken during a scheduler refactor.
