text: Title: select_related with ManyToMany through
  Body: **Describe the bug**
  Trying to query a ManyToMany through relationship and getting this error:
  ```bash
  ormar.exceptions.RelationshipInstanceError: Relationship error - ForeignKey EffortResource is of type <class 'int'> while <class 'weakref.ProxyType'> passed as a parameter.
  ```
  
  after running `await EffortStep.objects.select_related("users").all()`.
  
  Models:
  ```python
  
  class User(PublicIdMixin, ormar.Model):
      id = ormar.Integer(primary_key=True)
  
      class Meta(BaseMeta):
          tablename = "users"
  
  class EffortStepUser(ormar.Model):
      id = ormar.Integer(primary_key=True)
  
      class Meta(BaseMeta):
          tablename = "effort_step_x_user"
  
  class EffortStep(PublicIdMixin, DateFieldsMixin, TenantAwareModel, ormar.Model):
      id = ormar.Integer(primary_key=True)
      users = ormar.ManyToMany(
          User,
          through=EffortStepUser,
          through_relation_name="step_id",
          through_reverse_relation_name="user_id",
      )
  
      class Meta(BaseMeta):
          tablename = "effort_step"
  
  class EffortResource(DateFieldsMixin, TenantAwareModel, ormar.Model):
      id = ormar.Integer(primary_key=True)
      step: EffortStep = ormar.ForeignKey(EffortStep, name="step_id", nullable=False)
  
      class Meta(BaseMeta):
          tablename = "effort_resource"
  
  ```
