[FIX] link_tracker,website_links: use specific site url

- Create 3 websites and set a website domain for each
- Install the website_links module
- Go to Website > Configuration > Settings
- Select the website 3
- Go to website
- Menu Promote > Link tracking

The URL field uses the domain you are logged into the database
rather than the domain of the active website

The expected behavior is:
With an ICP set to URL1, a website 1 set to URL2 and a website 2 set to
URL3, going to the link tracker website page from URL3 but with website
1 selected should:

Show the current website domain as placeholder of the input -> URL2
Create link for that current website the user selected -> URL2
