fix(groups): Avoid segfault when resizing group audio window

Browse Source 
Avatars for group members currently in a call are resized depending on
the area they are displayed in. Previously a scrollbar would appear and
disapear based on the size of the contents. This resulted in
oscillations that ended in a SIGSEGV.

This fix avoids the oscillations by fixing the scrollbar to always be
shown
