UnitTests - Fixed IParsingService.ParseTitle mock
Scheduler - changed to ExecuteCommands almost immediately on startup and then at a 30 seconds interval
This is to aid in debugging tasks so they run right away
Misc fixes - Fixed rejection reason string for UpgradeSpecification, fixed Parser to use NLog instead of Debug.WriteLine()
ParsingService - fixed to use the inexact search function for series lookups and to use the parsed seriestitle when possible
