More Scan Loop Bugfixes (#1471)

* Updated scan time for watcher to 30 seconds for non-dev. Moved ScanFolder off the Scan queue as it doesn't need to be there. Updated loggers

* Fixed jumpbar missing

* Tweaked the messaging for CoverGen

* When we return early due to nothing being done on library and series scan, make sure we kick off other tasks that need to occur.

* Fixed a foreign constraint issue on Volumes when we were adding to a new series.

* Fixed a case where when picking normalized series, capitalization differences wouldn't stack when they should.

* Reduced the logging output on dev and prod settings.

* Fixed a bug in the code that finds the highest directory from a file, where we were not checking against a normalized path.

* Cleaned up some code

* Fixed broken unit tests
