Consider refactoring createProfile() function in IsProfilable trait

[cbj4074]

Per a discussion on Discord, 2018-09-27 11:47AM EST, @poppabear8883 noted the following observations:

the more i look at that method the more i want to move that logic into the IsProfilable
so that it looks more like:
$this->createProfile($model, $data);

and

public function createProfile($model, array $data) 
{
        $this->profilable()->create([
            'moniker' => $data['moniker'],
            'city' => $data['city'] ?? null,
           ...
        ]);
}

i much rather have those null coalesce ops once and not on every repository that uses the IsProfilable trait
and i am wondering if we can have a more fluent api with the repositories create method

We should investigate further and make the appropriate changes if necessary.
