The UI needs a page refresh to start working with no pre-existing authcodes

[jesuscript]

To reproduce:

1. delete ~/.parity/signer/authcodes
2. start parity as parity (note: without the "ui" command, or the bug won't show itself)
3. open 127.0.0.1:8180 in your browser
4. the UI gets stuck at "Connecting to the Parity Secure API" until the page is refreshed

I think you need to go to localhost:8080 which redirects you to 8180.

[jesuscript]

the hostname has to be 127.0.0.1, not localhost. Not sure how this makes a difference anyway, the page still won't update

Cannot confirm. localhost:8080 and 127.0.0.1:8080 both redirect me to 127.0.0.1:8180, which connects successfully and then shows "generate a Signer token". Tested on master.

Can confirm actually (on :3000), but had to delete restart parity twice after deleting ~/.parity/signer/authcodes for some reason. Will look into it.

Should be fixed with #3927
