Clickable persons chat middleware broken on multiple persons with same first name

[lieuwex]

Okay this is a fun one, with two people:

[
	{ "_id": "a", "profile": { "firstName": "Henk", "lastName": "Pietersen" } },
	{ "_id": "b", "profile": { "firstName": "Henk", "lastName": "Kaazig" } }
]

the middleware will currently generate

<a id="a"><a id="b">Henk</a></a> <a id="b">Kaazig</a>

We should find a way to prefer the 'Kaazig' immediately, since it's surname is behind the first name.
