[FIX] web_editor: hide "Open in New Window" option for emails

When `link_tools` was introduced at [1], the selectors to the
`is_new_window` input were copied from `link_dialog`'s `_onURLInput`
without being adapted. Later the code was refactored into `link` at [2]
because they were an exact match.
This commit updates the selectors to also match the field inside the
link tools.

Steps to reproduce:
- Edit Home page
- Drop a "Banner" block
- Select the "Contact Us" button
- Change the URL to an e-mail address
=> The "Open In New Window" field was still available
