Fix of the issue that VoLTE checking
state label was cut off due to
improper setMinimumWidthToFitText()
method behavior when text is placed
in box with rounded corners.
Introduced the new logic.
From now on, every button can be tri-state, that is,
OFF/ON/Transiting whereas the Transiting state is
marked with the 'cheking...' caption written on the
button.
