fix(Communities): ensure community chats exist in memory upon spectating

When a community link is shared with a user and that user visits that community, it turns out that the chat objects for that community have not been created yet.

This results in chat data being malformed/non-existent until another message signal is processed that updates the chats in memory. This update can someimes occur earlier, sometimes later, which is why the issue isn't always reproducible.

This commit ensures we're loading chats from status-go again upon spectating, to ensure they exist in memory when we try to access the data in the UI.

Closes #8361
