Bug fix: populate block/mute status on mute_card and block_card creation

The issue:

Block and mute status aren't being created on initial load of settings menu, so mute and block buttons will show in that menu in their unblocked/unmuted states (despite everyone in the lists being blocked or muted). This appears to have been an issue even on instances back on 2.2 and still today.

The fix: Just fetching the relationship info on modal creation

Hope this was clear enough! Let me know if you have any questions
