assertDatabaseHas should allow multidimensional array

[zsoltjanes]

I would like to validate multiple database records, and now I have to make it separately.

$this->assertDatabaseHas('users', [
   'email' => $users1->email,
   'is_active' => 0,
]);
$this->assertDatabaseHas('users', [
   'email' => $users2->email,
   'is_active' => 0,
]);

It would be elegant if I can use multidimensional array like:

$this->assertDatabaseHas('users', [
   [  
      'email' => $users1->email,
      'is_active' => 0,
   ],
   [  
      'email' => $users2->email,
      'is_active' => 0,
   ],
]);

For solution first I would suggest make a new Arr helper which validate that the given array is multidimensional. I already make a pull request but its closed. #38916
For second step we should improve the assertDatabaseHas function with Arr::isMultidimensional. It should check that the given data is a multidimensional and if its true we should foreach throught the given data array.
