Web: Deleting the last post in a channel causes the channel to only display a loading spinner

Description

Environment: Firefox/Mac on community-release running 5.14 RC4 and locally on master

Repro steps:
1) View an empty channel (such as a DM channel with a user you've never messaged)
2) Make a post
3) Delete that post

Observed: The channel is replaced with a loading spinner. Switching channels or making a post doesn't fix this, but refreshing does
Expected: The channel is still displayed
