Places data engine: Rename model role name "index" to "id"
Review Request #126851 - Created Jan. 23, 2016 and submitted
I wrote a qml applet using the places data engine and noticed that I can't access the index variable of ListView items because it gets overwritten by the places model.
This patch renames the "index" role name to "id" in order to avoid this naming conflict.
I couldn't find any other model that is using the places data engine so I hope renaming the model role is fine.
The provided model still works and I tested the "Setup Device" and "Teardown Device" operations of the service.
The operations "Show" and "Hide" don't seem to work anyway and the others were not tested.
