TT#109166 Fix 6f2cc8: maximize and minimize buttons doesn't work

The min/max buttons did not work for dynamic block.
It is a regression of the initial commit d0f339eef7 and 6f2cc8b717.

Fixing it by removing min\max buttons from dynamic popups. It looks like the information on those popups will not look better after maximization (subscriber prefferences \ CallForwarding section \ question mark icons to activate popups).
