test: improve reliability of status action logs tests

[simonfernandes]

Description

Hopefully fixes the flakiness we are seeing with the status action logs tests currrently.

1. Instead of waiting for a predetermined amount of time for the status actions to complete, this will keep polling the status actions logs in the beforeEach() to ensure they have successfully completed.
2. Also simplifies a test that was creating a new proposal and waiting unnecessarily.
