Manual interventions:
• decorators on the same line for service and controller
injections and most computed property macros
• preserving import order when possible, both per-line
and intra-line
• moving new imports to the bottom
• removal of classic decorator for trivial cases
• conversion of init to constructor when appropriate
Protect against case where an alloc has no services and avoid
dereferencing null.
Here, we ensure that the model and test serializers mimic the API by
having nil TaskGroup.Services instead of an empty array.
