Last version assignRole() bug with loaded roles

[scippio]

Description

Hi I have a problem with last version 6.15.0.

I have environment with central db + tenants (https://tenancyforlaravel.com).
$user = ..
inTenant($tenant, function () use ($user){
setPermissionsTeamId(1);
$permissions = .... (factory)
$user->asignRole(...); <- there is a problem...

//---
after assign, the user have this role and I can continue with my test. But after upgrading to 6.15.0 there is no this role in user->roles (is in tenant db, that's ok).
//---

})

(I have my own load('roles') method in User, when I parent::load('roles') in tenant and outOfTenant(fn()) I loading central roles and merge it... but I don't think it's related... everything works as it should before 6.15.0. .. )

• Maybe Fixed bug of loading user roles of different teams to current team #2803

In my opinion it was not a bug, just a convenience change

A breaking test that reveals the problem is welcome.
