Comment 2 for bug 1920234

Here is a branch that implements John's first recommendation (not creating a duplicate "System-created bucket", and reflecting all changes made to the original bucket in the carousel): user/sandbergja/lp1920234-no-duplicate-system-generated-buckets

...and a link: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sandbergja/lp1920234-no-duplicate-system-generated-buckets

...and some notes for testing:

1. Create a record bucket
2. Add some records to it
3. Create a carousel from your bucket
4. In Local Administration > Carousel Library Mappings, set up your new bucket to display in your library's public catalog.
5. Confirm that your records are displaying in the carousel.
6. Remove some records from your bucket, and add some new ones.
7. Refresh the public catalog in your browser, and note that the carousel contents have updated according to the changes you made to your bucket.
