QtCreator never really remembers default target device

As described here:

http://stackoverflow.com/q/33935147/607407 (text is: When trying to compile android application in QtCreator, I'm first asked to select target device. I select it and check "Allways use this device..." )

No matter whether you click "Allways use this device" or not, the popup appears every time. This significantly prolongs already long compilation.
