room names aren't upheld in group room list in rightpanel

[ara4n]

if i add #matrix-fr:matrix.org to +community:matrix.org it turns up as 'Unnamed room' in the rightpanel, rather than correctly falling back to being shown by its alias as per the LeftPanel

This is due to -fr not having a Canonical Alias set it seems

and as per the Groups API draft we don't get any non-canonical aliases:
