OAuth flow with assembly loading

[cmdcolin]

Currently, there still could be an issue if user:

• logs in
• open a view
• open track
• leave the app until token expires
• go directly to the assembly selection page in linear view

This may result in an error, but now refreshing the page after this error at least will request a new token.
