[BUG] Firepad/brace text editor causes route error on load

[jake-pauls]

Describe the bug
When loading the Editor.vue component, a session ID is passed to the current browser's url in order to provide synchronous editing. In doing this, the Vue router isn't aware of this route and instead returns a 404 (that, fails to load?).

Although this doesn't break the feature, it's worth looking into.

Steps to Reproduce
Steps to reproduce this bug:

1. Navigate to Editor.vue on the firepad-integration branch
2. Open the developer console to see the error

Expected behavior
The Vue router recognizes that this path is meant to have a session ID and it doesn't return the 404.

Additional Info
This could be fixed when we bring together the editor and the video call components.
