Issue:
Bug when assigning role to user that has same role in a different team
### Bug Description :
This happens when the user has role for ex: `admin` in team `A` and want to assign it same role but in team `B`.
What happens is that the user doesnt get assigned that role `admin` in that team `B` cuz in the treat that the method `assignRole()` sits in, the the `$this->roles` relation property is called to get user's roles and run `array_diff` on those currentRoles and the new Roles to assign (in this case **admin** role), the problem is that if the roles are already loaded on the user object before the teamsId was changed, then the `$this->roles` would return the role `admin` cuz the user has it in the other team not this one, thus the array_diff would return an empty array thus no roles would be assigned, 

#### HasRoles trait, assignRole method :

https://github.com/spatie/laravel-permission/blob/9d4fa2987f9b745854a13e1b36ba68e0b6dd4bdb/src/Traits/HasRoles.php#L154-L159



### Fix Suggestion :
We should instead of calling `$this->roles` which could load the already loaded roles, we should use `$this->roles()` which reload the roles with taking into consideration the new team_id that's set on the session thus no roles interference would happen.
