Loading project in editor causes api response of 401

[benjiwheeler]

To repro:

1. be signed in, and viewing editor
2. do File->Load from computer and load an sb* file
3. view javascript console

you'll see: Failed to load resource: the server responded with a status of 401, from the endpoint api.scratch.ly/projects/undefined

Gets this too. But since the project loads properly, it seems minor

Seems like this may be addressed by scratchfoundation/scratch-gui#5418 and #3674
