Fix bug where a panel recieve extra top border

https://github.com/twbs/bootstrap/issues/13734

A panel placed inside of a collapsible panel recieve extra top border.

This commit reduces the effect of a selector to apply a border only to
the collapsible panel body itself, not to any panel placed within it.
Resolves Issue #13689

Doing this the right way this time. Hiding .panel-footer top border when
preceeded by a .list-group. This should resolve the "double border"
issue.
