Fix behavior when not entering the correct URL format

When adding a new account on Drive, and not entering the correct format of URL, a popup proposes to downgrade Drive version instead of explaining to fix the URL format.

Steps to reproduce:
1. Launch the Nuxeo Drive App
2. Go to Accounts - Add Account
3. Enter the URL. URL should contain the query parameters.
for ex. https://drive-2021.beta.nuxeocloud.com/nuxeo/login.jsp?requestedUrl=ui%2F
4. Enable - Use Legacy Authentication
5. Click on Connect
[Note: Issue is reproducible with Features - Auto Update option enabled or disabled]
