url: added authuri when login information is requested (issue3209)

url: added authuri when login information is requested (issue3209)

When users are using a revset they can get multiple password prompts.
This prompts have no extra information about which password is being requested
so I added the authuri to the prompt to make it recognizable.

As in:
$ hg log -r "outgoing('https://bitbucket.org/mg/test') -
outgoing('https://bitbucket.org/nesneros/test')"
http authorization required
realm: Bitbucket.org HTTP
user: interrupted!

I changed it to describe the url when prompting for password.
As in:
$ hg log -r "outgoing('https://bitbucket.org/mg/test') -
outgoing('https://bitbucket.org/nesneros/test')"
http authorization required for https://bitbucket.org/mg/test
realm: Bitbucket.org HTTP
user: interrupted!
