Latest Master Branch: Invalid Token - UI does display token modal

[CraigglesO]

Blocked connection from http://localhost:8180 using invalid token.
even using --ui-no-validation or --ws-origins all I can't get the parity to work with the UI. No modal to give a valid token showing up.

Probably related to #5722 - should we track this in one ticket?

It's fixed in #5710, let's track it as one.

No, I'm sorry but I think this is a JS issue that has not been resolved even in your PR. I pulled it and I still got:
Connecting to the Parity Node. If this informational message persists, please ensure that your Parity node is running and reachable on the network.
while, obviously it should be asking for a new token to use.

You need to build with cargo build --release --no-default-features --features ui cause it's indeed JS stuff that I broke and you need to recompile it as well.
