[xrandr] Fix 453 devices issue (#455)

Browse Source 
* [xrandr] Fix bug 453, clean up data model

* Fix: 'devices' was originally not a list, just assigned each time it
was parsed. Made that a list and appended to it.
* Removed distinction between unassociated/associated devices
* Added test for @marcin-koziol's problem
* Put tests into separate test methods

* Formatting cleanup

* Backwards compatible type syntax
