[patch] validation for missing core=True in ForeignKey relations wrong

get_validation_errors must check edit_inline attribute

This has been fixed at some point since it was filed. The error is only raised if edit_inline = True.

Nope.

I get this message:

popkern.nextrech: At least one field in Nextrech should have core=True, because it's being edited inline by tarifkunde.Tarifkunde.

With these models:

class Nextrech(models.Model):
    id = models.IntegerField(primary_key=True)
    tarifkunde = models.ForeignKey(Tarifkunde, db_column='tarifkunde', related_name='nextrech_entry')
    knextrech = models.ForeignKey(Knextrech, db_column='knextrech')
    wann = models.IntegerField()
    beginn = models.IntegerField()
    ende = models.IntegerField()
    anzahl = models.IntegerField()
    timestamp = models.DateTimeField()
    class Meta:
        db_table = 'nextrech'

class Tarifkunde(models.Model):
    id = models.IntegerField(primary_key=True)
    kunde = models.ForeignKey(Kunde, db_column='kunde')
    tarif = models.ForeignKey(Tarif, db_column='tarif')
    tarifname = models.ForeignKey(Tarifname, db_column='tarifname')
    dienst = models.IntegerField()
    anzahl = models.IntegerField()
    beginn = models.IntegerField()
    ende = models.IntegerField()
    ablauf = models.IntegerField()
    notiz = models.IntegerField()
    info = models.ForeignKey(String, db_column='info')
    infotext = models.CharField(maxlength=255)
    rechnung = models.TextField()
    nextrech = models.IntegerField()
    timestamp = models.DateTimeField()
    class Meta:
        db_table = 'tarifkunde'

cc to mtredinnick since he closed this ticket.

This is a bit subtle. It's triggered by the Tarifkunde.nextrech field -- which is why a related_name is required on Nextrech.tarifkunde. Without that (and after fixing the other fields so that this imports), no error. It's a bug, but triggered by strange circumstances. Fixing it now.

(In [3275]) Fixed #1578 -- fixed a corner-case where we still wanting core=True attributes on a model that was not being edited inline.
