Many to Many doesn't work with own relfield

[adkurz]

With latest commit (master) and with v1.7, there is a problem with many to many relations with the experimental new column names.
The ugly table looks like this (german field names):

table rechtehg (
id int,
bid int,
hgid int
)

bid means user id, hgid means main group id
In Cortex model, fieldconf looks like this:
Model User:

'berechtigte_hauptgruppen' => [
  'has-many' => ['\Model\MainGroup', 'berechtigte_benutzer', 'rechtehg'],
  'relField' => 'bid'
]

Model MainGroup:

  'berechtigte_benutzer' => [
  'has-many' => ['\Model\User', 'berechtigte_hauptgruppen', 'rechtehg'],
  'relField' => 'hgid'
]

But if I use the relation, for example with a contains it doesn't work:

$mainGroup = new \Model\MainGroup();
$mainGroup->virtual(
  'selected',
  function ($self) use ($user) {
    if (is_null($self->berechtigte_benutzer))
      return false;
    return $self->berechtigte_benutzer->contains($user);
  }
);
$list = $mainGroup->find();

Cortex generates following wrong sql statement:

SELECT "id","bid","hgid" FROM "rechtehg" WHERE "berechtigte_hauptgruppen" IN ($1,$2,$3,$4,$5,$6,$7,$8,$9,$10,$11,$12)

The column name after the "where" does not exist, it should be hgid or bid.

I just checked that once more and was not able to reproduce the issue.. looks good to me with the same setup
