button height should not change

[Nicolò Chieffo]

Binary package hint: update-manager

"Check" and "Install updates" buttons have a variable height, depending on the update phase.
Scenario:
- launch update manager
- you'll see a window saying "starting update manager" with a progress bar
!!! in this phase the 2 buttons are taller
- when the progress windows closes the update manager window is focused
!!! in this phase the 2 buttons are smaller if there is no update, otherwise they remain the same as before

It seems that the height depends on the way buttons are packed. Maybe they are set to automatically expand?
