Scan Loop Fixes (#1572)

* Cleanup some messaging in the scan loop to be more context bearing

* Added Response Caching to Series Detail for 1 min, due to the heavy nature of the call.

* Refactored code to make it so that processing of series runs sync correctly.

Added a log to inform the user of corrupted volume from buggy code in v0.5.6.

* Moved folder watching out of experimental

* Fixed an issue where empty folders could break the scan loop

* Another fix for when dates aren't valid, the scanner wouldn't get the proper min and would throw an exception (develop)

* Implemented the ability to edit release year from the UI for a series.

* Added a unit test for some new logic

* Code smells
