The "Apply" button is not handled properly in the Device options page (as a workaround for QTCREATORBUG-1675).

To reproduce:
1) Go to Tools->Options->Devices
2) Create a generic linux device using hostname "host1" (cancel the test).
3) Click "Apply"
4) Change hostname to "host2"
5) Click "Cancel"

Expected Outcome:
The Device options page has the new device with hostname host1.

Outcome:
The device options page has the new device with hostname host2.
