perf(marmot): skip the relay-icon lookup for rows that show members' faces

Browse Source 
An unnamed, avatarless group (a White Noise 1:1) draws its members, but the row resolved
the group picture first, a NIP-11 relay-info fetch per row that was then thrown away. The
picture is now resolved only on the branch that draws it.
