Use context theme wrapper with specific theme when inflating button

This fixes the theme being incorrect after rotating.

Test: manual - 1) have auto rotate on & change the theme
               2) add some bubbles, expand them, check the manage
                  button theme
               3) rotate the device, observe that the manage button
                  theme remains the same
