JSDebugger: Only hit breakpoints in user code

Check that the topmost stack entry is a user defined ScriptFunction.
This avoids hitting the anonymous functions used for bindings, e.g.

onClicked: Qt.quit()

leads to script code

(function onClicked() { Qt.quit(); })

which will be hit twice for the debugger: Once for the function call
itself, then for the execution of Qt.quit().
