chore(aci): default issue alert dual write to True

[cathteng]

List of changes:

1. Remove usages of issue alert dual write flag
2. Add option in create_project fixture to create the default detectors and set it to False
3. Modify the relocation logic for a project to not create the default detectors when creating the project in SaaS because we'll be migrating the default detectors over
4. Add logic to enforce a single error detector & issue stream detector per project. Allow modifying fields on the detector because different names than the default are expected in some tests
5. Update logic to use create_detector(project=project) instead of create_detector(project_id=project_id), which causes issues in the modifying fields step above because we'd pass project and project_id to detector.update(**kwargs)
