Tweak the Get[Filtered]RecordedList() services API calls.

Change GetRecordedList() to return recordings from the Deleted group.
This is consistent with the equivalent Myth protocol functionality.
Remove GetFilteredRecordedList() and add the optional filter
parameters to GetRecordedList().  They already used the same function
internally.
Remove GetFilteredLiveStreamList() and add the filtering parameter to
GetLiveStreamList().

They used the same funtion internally.  This also makes it consistent
with all of the other Get*List() calls after GetFilteredRecordedList()
was similarly removed.
