bug: missing cache invalidation when renaming community

steps to reproduce:

1. create a community
2. change its name
3. load own user profile

expected results:

• community's new name is displayed both in the "Moderates" and "Subscribed" boxes

actual results:

• new community name is displayed in the "Moderates" box
• community's old name is still displayed in the "Subscribed" box

additional notes:

• the renamed community's new name becomes visible after subscribing to some other community
• sorry for posting this here, but, i don't want to give microsoft my telephone/ID/firstborn/etc which is required to open an issue on github these days
