Collective name use circle Sanitizedname and not Displayname

[wargreen]

Describe the bug
Since the sanitizedname is used, some char as "<" seem escaped and not shown in the collective names, but correctly changed and displayed in the circle's name.
The difference of names can lead to misunderstand the link between collective and circles.

To Reproduce
Steps to reproduce the behavior:

1. Go to Collective
2. Click on create collective or edit name of a collective, with a name content "<"
3. The collective name don't show this char
4. Look the circle name in the contact app and see that is not the same.

Expected behavior
The collective' name and the circle's name are the same.
