In <a href="http://buddypress.trac.wordpress.org/changeset/11959">r11959</a>, the banned group members check is using the wrong conditional.
This caused legitimate group members to never see the "Comment" button in
the activity stream.

This commit reverses the check and adds some unit tests (which should have
been written beforehand!).

Anti-props r-a-y.

See <a href="http://buddypress.trac.wordpress.org/ticket/4429">#4429</a>.

Fixes <a href="http://buddypress.trac.wordpress.org/ticket/7854">#7854</a> (3.x branch).</pre>
