[debug] Inline frame decoration is not shown when reached from a different line

[mvtec-richter]

Bug Description:

Steps to Reproduce:

1. Create a javascript file in Theia with following content:

a = 1;
b = 2; throw new Error('test');

2. Set breakpoint on first line
3. Enable "Uncaught Exceptions"
4. Launch debugging with "Run current file (pwa-node)" -> the execution pauses at the first line
5. Continue execution -> the execution halts with an exception at the throw statement

What happens: There is no inline frame decorator in front of the throw statement

What should happen:
Compare this to:

1. Restart execution
2. Step over -> Execution pauses at first command in second line
3. Continue
   There is a inline frame decorator clearly marking, that the exception occurred at the throw statement.

The logic in DebugEditorModel only takes into account the case, that the second statement in one line was reached right after pausing at another statement at the same line. However, there are other ways to reach nested statements. The logic should be independent of local state (this.topFrameRange).
