Clear "session resume cache" after creating a topic

I just created a topic, and after creating the topic I clicked on "New Topic" again and saw the content from my previous topic prefilled in the form.

This is an awesome feature so you don't loose the progress when you accidentally reload the page, but it seems that the "session resume cache" isn't cleared when you actually go ahead and create the topic.

Ugh, yes! This is in my bug list, but I was really struggling to figure out how to get the session cache to clear properly on successful form submission with session-resume. 🥵
