Can't create an employee associated to another shop with email already used in database

[PrestaEdit]

Prerequisites

• I understand and accept the project's code of conduct
• I have already searched in existing issues and found no previous report of this bug.

Describe the bug and add screenshots

Once you enable the multishop and having two shops, you are able to create somes employees with shop associated.

If you try to use the same email address, it will fail because it's already exist, even if it's not associated to the same shop.

Expected behavior

Be able to use the same address email within each shop for an employee account.

As you can use the virtual uri to reach the Back Office of the specific shop, you could be able to have an employee with the same email address but with a different profile and/or ajusted for this shop.

Steps to reproduce

1. Enable multishop
2. Add another shop
3. Add an employee (don't use the SuperAdmin profile, it's a special one)
4. Associate only one shop
5. Change your shop context to the next shop
6. Add an employee (again, don't use SuperAdmin profile) with the same email and associate it your other shop to it
7. See the result error

Hello,

I don't know if this is really a bug? Is there any evidence that it worked like this in previous versions? It looks more like an evolution.

If we take the request, we should check at the same time that the e-mail address exists in the context of the associated stores. It may seem strange for administrator to create employee ?
