Debugger: Minor refactor.

TeamDebugger:
- Rather than instantiating the DebuggerInterface directly, we now
  expect it to be given to us externally. This allows TeamDebugger
  to be agnostic of where the team actually resides.

Debugger:
- Create and initialize DebuggerInterface before passing it on to
  TeamDebugger.

No functional change.
