RelatedManager does not work with db_manager

[craig.kimerer@…]

RelatedManager is always selecting from the db_for_read provided by the router even if db_manager() is used.

With the following models:

class ModelA(models.Model):
  foo = models.IntegerField(default=0)

class ModelB(models.Model):
  bar = models.ManyToManyField(ModelA)

Running the following in shell:

>>> mod_a = ModelA.objects.create(foo=1)
>>> mod_b = ModelB.objects.create()
>>> mod_b.bar.add(mod_a)
>>> mod_a.modelb_set
<django.db.models.fields.related.ManyRelatedManager object at 0x102b4da50
>>> mod_a.modelb_set.db
'default_slave'
>>> mod_a.modelb_set.db_manager('default').db
'default'
>>> mod_a.modelb_set.db_manager('default').all()[0]._state.db
'default_slave'

For the record, it also affects reverse FK relations.

(In [12993]) Fixed #13358 -- Ensured that db_manager() can be used to override database routing on M2M, reverse FK and generic key queries. Thanks to Craig Kimerer for the report.
