[autotests] Extend StrutsTests for setup on mobile

This testcase tries to emulate the panel setup on the phone,

- Window placement strategy is set to maximizing
- Top panel with height of 60
- Bottom panel with height of 150

However this is still not complete testcase, some todo items:

- Create Plasmashell desktop window before creating panels
- Create normal window and verify if its placement/position is right
