inspector: do not hardcode Debugger.CallFrameId in tests
Debugger.CallFrameId is defined as an opaque string [1].
Some tests currently hardcode the value, relying on undocumented internal details of V8. This makes it hard for V8 to change the internal representation.
We should instead use the reported call frame id from the Debugger.paused event directly. This is how every inspector client does it.
