Fixes to javadoc build warnings

Some small javadoc fixes to remove warnings during build
OF-805 [MUC] OF does not return all affiliated users when requesting multiple affiliations

When requesting:
<iq type="get" to="6ace0fd2f59f13c2484336dd06b4462a@bizmanager.msz006" id="getRoomMemberList">
<query xmlns="http://jabber.org/protocol/muc#admin">
<item affiliation="member"/>
<item affiliation="owner"/>
<item affiliation="admin"/>
</query>
</iq>

Openfire does only return admins (the last requested affiliation).
This fix rectifies this.
Remove dispensable logic in the IQOwnerHandler, which deals with MUC affiliation changes

MUC affiliations are managed in the #admin namespace, not in the #owner namespace.
This is already a minor contribution to OF-178 (Updating MUC to latest version).
