[GitHub] [superset] michael-s-molina opened a new pull request, #24550: fix: Deque muteted during iteration

michael-s-molina opened a new pull request, #24550:
URL: https://github.com/apache/superset/pull/24550

   ### SUMMARY
   Fix a bug in https://github.com/apache/superset/pull/24488 that happens when running on SQL Lite. There was an event being registered inside another event and causing a `deque mutated during iteration error`. According to SQL Alchemy [docs](https://docs.sqlalchemy.org/en/20/core/event.html#sqlalchemy.event.listen):
   
   > The [listen()](https://docs.sqlalchemy.org/en/20/core/event.html#sqlalchemy.event.listen) function cannot be called at the same time that the target event is being run. This has implications for thread safety, and also means an event cannot be added from inside the listener function for itself. The list of events to be run are present inside of a mutable collection that can’t be changed during iteration.

Review Comment:
   @hughhhh I set `commit=False` to mimic the other tests in the `ssh_tunnel/commands` folder which use `CreateSSHTunnelCommand` that has `commit=False` by default. If we enable the commit in this test or in the command ones, they will fail because there's no database with `id = 1`. If an actual commit is required for the tests, I suggest opening a follow-up PR and fixing not only this test but the ones in the `commands` folder.
