Follow-up to regressions from #1928, this PR:
- Fixes response models for queue endpoints, which had incorrect model
- Adds tests for queue get, queue match, and exclusions add / remove to
ensure regressions like this can be caught via tests. This involves
starting a new crawl in test_run_crawls() instead of relying on implicit
running via fixtures, make it easier to test crawl while it's running.
- Adds additional typing for crawls apis, including making
delete_crawls() have correct typing, consistent derived class override
- Adds check to ensure queue + exclusion operations can not be called
when crawl is not running
