More Bugfixes (EPUB Mainly) (#2004)

* Fixed an issue with downloading where spaces turned into plus signs.

* If the refresh token is invalid, but the auth token still has life in it, don't invalidate.

* Fixed docker users unable to save settings

* Show a default error icon until favicon loads

* Fixed a bug in mappings (keys/files) to pages that caused some links not to map appropriately. Updated epub-reader to v3.3.2.

* Expanded Table of Content generation by also checking for any files that are named Navigation.xhtml to have Kavita generate a simple ToC from (instead of just TOC.xhtml)

* Added another hack to massage key to page lookups when rewriting anchors.

* Cleaned up debugging notes
