Community account mute does not work

Communities have two level of mutes, post level and account level. Currently post level mutes work, account level does not work.

Prior to recent Hivemind updates, account level mutes worked by assigning the muted role to an account. This was a feature I have personally used a lot in the past to mute known spammer accounts across multiple communities.

Currently, assigning the muted role to a user does not mute their content from the community.
