Avoid hitting the anonymous wrapper functions in .qml file

QtDeclarative generates anonymous wrapper functions for QML bindings
and slots, e.g.

    onPressed(): { i++ }

becomes

(function (onPressed) { i++ } )

v8 will by default break when the anonymous function is called, not
when the actual code is executed. If we now hit this outer function
we'll relocate the breakpoint to column = 1, and continue.
