room filtering should normalize room names (i.e. ignore diacritics)

### Steps to reproduce

1. click the search button on top of the room list view
2. start typing the name of a room containing diacritical marks

### Outcome

#### What did you expect?

If a room is named "mêmes", it should match when I type "memes"

#### What happened instead?

It matches when I type "me" but not "mem".
