[10.x] Fix Laravel Missing Validation rules not working with nested array data

[aabadawy]

  This PR let next validation rules work fine with nested array data dependacies.

• missing_if
• missing_unless
• missing_with
• missing_with_all

I also add assertions for each test validation rule of them

After this PR

this next validation rule will throw validation errors

use Illuminate\Support\Facades\Validator;

$rules = ['foo.*.bar' => ['missing_if:foo.*.fez,1']];

$data = [
    'foo' =>  [
        [ 
            'bar' => 'should be missing',
            'fez' => 1 
        ],
        [
            'bar' => 'can be filled',
            'fez' => 10,
        ]
    ]
];

Validator::validate($data,$rules);
# this will throw validation exception with message The foo.0.bar field must be missing when foo.0.fez is 1

Before this PR

These rules escape the validation without throwing any validation error, As the asterisk had not been replaced with the current array row index.

Your array isn't nested enough. You don't have have foo.*.bar, you just have foo.bar.

@taylorotwell I edited The Description Example, My Bad.

You can check that: missing_if and other missing validation rules are not exist at dependentRules
Which is my PR fix.
Also you can see

framework/src/Illuminate/Validation/Validator.php

Line 619 in ced4689

if ($this->dependsOnOtherFields($rule)) {

this method relace the asterisks with correct key.
How it will be replaced if the (missing_if,missing_unless,..etc) not exists in $dependentRules property ?
