Fix return value of query scopes from parent class

[sforward]

This PR fixes the return value of query scope methods that are defined in a parent class of the target model. At the moment the return value contains the class name where the method is located: @method static \Illuminate\Database\Eloquent\Builder|PostParent active(), and with this change it correctly becomes @method static \Illuminate\Database\Eloquent\Builder|Post active(). See included test for more context.

(I included a commit to update a snapshot that failed the test suite, unrelated to this change.)
