Collection Template settings should be applied if differ from same fields in Publisher Template
cc @jordandc @douglassue @kin @ESgitlab
Context
There are a few settings that exist in BOTH Collection AND Publisher Templates - namely Publisher and Self Citation URLs
While testing #984 (closed), I found that if I create a new book that has BOTH a Collection AND Publisher Template, the Publisher URL and the Self Citation URLs from the Publisher Template is carried over to the book, not the ones from the Collection URL.
Proposal
The Collection Template settings should be applied if they differ from the same fields in the Publisher Template. This is how the Bookshelf team's clones currently work.
PRIORITY -
If this breaks how those cc'd on this ticket clone / template new, frequent books it will be needed for deployment - further research with those cc'd needs to be done to determine this, looking at migrated data.
