Enable adding user logins similar to whitelisted 

Currently when a requested new login string to be added to the project includes the whitelisted login string, user will not be  added.
E.g: when calling:
project.import_users([{user: {login: 'simple_user@example.com'}, role: 'dashboardOnly'}], domain: 'example-domain', whitelists: ['user@example.com'])
the user 'simple_user@example.com'} will not be added to the project
