[6.x] Only restore common relations

[taylorotwell]

Fixes #26126

We only want to restore relationships that are common amongst all models in the collection. Otherwise there will be errors be attempting to restore the collection.

One downside to this PR could be potential performance implications of getting the queueable relationships for each model in the collection. I did this in a collection of about 1000 models and it took 0.70ms on my local machine.

There is an error with array_intersect when ...$this->map->getQueueableRelations()->all() returns less then two arrays

[driesvints]

@oleksiyPetlyuk this should be fixed in the latest release.

[taylorotwell]

What exactly is getQueueableRelations returning for you?

[GC-Mark]

We are also seeing ErrorException: array_intersect(): at least 2 parameters are required, 1 given in Illuminate/Database/Eloquent/Collection.php:579

For us, getQueueableRelations is returning this...

$relations = $this->map->getQueueableRelations()->all();

dump($relations);

array:1 [
  0 => array:1 [
    0 => "account"
  ]
]

Hope that helps

[taylorotwell]

OK Thanks that is helpful. Fixing now.
