tests: rw: Make things pass without rhbz dev permissions

All these tests were written with implicit Fedora and RHEL developer
permissions, since that's what my bugzilla.redhat.com account has.
This is a big rework to make things pass and get maximum test
coverage with an unprivileged account.

The main bit is we need to use more self created bugs, vs pre-existing
bugs. This necessitates a bunch of messy changes scattered everywhere
