Metadata Optimizations (#910)

* Added a tooltip to inform user that format and collection filter selections do not only show for the selected library.

* Refactored a lot of code around when we update chapter cover images. Applied an optimization for when we re-calculate volume/series covers, such that it only occurs when the first chapter's image updates.

* Updated code to ensure only lastmodified gets refreshed in metadata since it always follows a scan

* Optimized how metadata is populated on the series. Instead of re-reading the comicInfos, instead I read the data from the underlying chapter entities. This reduces N additional reads AND enables the ability in the future to show/edit chapter level metadata.

* Spelling mistake

* Fixed a concurency issue by not selecting Genres from DB. Added a test for long paths.

* Fixed a bug in filter where collection tag wasn't populating on load

* Cleaned up the logic for changelog to better compare against the installed verison. For nightly users, show the last stable as installed.

* Removed some demo code

* SplitQuery to allow loading tags much faster for series metadata load.
