Not able to login to bitbucket server with @ in username

Replicate Steps:

1. Click on Add Account
2. select Bitbucket server as hosting service
3. mention username which has @ in username. We are using email as username
4. Refresh password with correct password

Issue Message:

Invalid URI: The host name could not be parsed.

If you see host name in Authentication tab of options then you will find that, parsing of URL is wrong.

It is parsing host with first @ character instead of last @.

This issue is bit critical for us because our whole organisation is not able to use Bitbucket server due to this issue.
