pseuCoDebugger drops Stackframe information

The pseuCoDebugger component fails to compute some data in Analyzedstate.agents[].frames which results in some Agents of the debugger not being able to fast-forward, even though they are enabled.

Steps to reproduce:

1. Open a file that causes the bug
2. Click the pseuCo debugger action
3. Click fast-forward as long as this agent can act on Agent 0 and let the fast-forwarding terminate
4. Try to fast-forward a single line on Agent 7

Expected behavior: Agent 7 fast-forwards from line 5 to line 6.

Actual behavior: The fast-forwarding is immediately cancelled, as _evaluateFastForward cannot determine the agent's frame.

I tried to bug hunt the issue by looking into the analyzeState routine, to no avail.
