sqlbrowser example: fix ugly margin around ConnectionWidget 

When a layout is used to arrange the children of a non-top-level
custom widget, the layout's contentsMargins need to be manually set to
zero to avoid extra empty space around the widgets, misaligning it
w.r.t. its siblings.

Add the necessary call.

Amends 2690822428, which, however,
inherited the missing margin adjustment from older code.
