[BUG] nextUrl=undefined

[kavilla]

What is the bug?

There are periods where nextUrl is equal to undefined so then when I successfully log in it takes me to /app/undefined and I get an Application Not Found error.

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Download a new distribution
2. Log in
3. See Application Not Found

(Might not be guaranteed reproduce steps)

What is the expected behavior?
I know previously this value would be empty and if it's empty it would re-route to the default route which in most cases would be home. However, I know post Node 14 upgrade undefined has become more explicit as value. So it might be accidentally being set as a value instead of empty

What is your host/environment?

• OS: Mac
• Version: 2.0.0-rc1

Do you have any screenshots?

Do you have any additional context?
This could be related to the fix for this issue: #926.

This also is a blocker for tests as well because tests could be hitting this undefined page and then are unable to navigate.
