More Scan Loop Fixes (#1473)

* Added a ToList() to avoid a bug where a person could be removed from a list while iterating over the list.

* When deleting a series, want to read page will now automatically remove that series from the view.

* Fixed a series lookup which was ignoring format

* Ignore XML comment warnings

* Removed a note since it was already working that way

* Fixed unit test
