fix: tests on test backend (#1535)

* refactor: logic if storage plugin is open/closed

Also address a small typo in attribute check in open_storage()

* refactor: split test backend shutdown sequence

This should workaround a thread and storage timing problem.

* fix: move bot_thread to init

* test: disable failed circular dependency test

* docs: add test fixes to CHANGES
