Stackswitcher buttons in gnome-software are not themed alike

[Amr Ibrahim]

In gnome-software, the theming of the stackswitcher buttons at the top 'Installed' and 'Updates' is different than 'All'. The 3D effect is only visible in 'All' when selected. The three buttons should have the same effect.

No gnome-software, o tema dos botões stackswitcher no topo 'Installed' e 'Updates' é diferente de 'All'. O efeito 3D só é visível em 'All' quando selecionado. Os três botões devem ter o mesmo efeito.
