[7.x] Fix Validator, getPrimaryAttribute returns wrong attribute

[tobiasnitsche]

When I want the primary attribute for "1.10", I receive "*.1" and not the expected "*.10". It can be solved with the parameter strict=true of the function in_array.

Here is the testcase :

Parameter $attribute: 1.10

Return: *.1
Expected return: *.10

$this->implicitAttribute:

Array
(
[*.0] => Array
(
[0] => 1.0
[1] => 2.0
)

[*.1] => Array
    (
        [0] => 1.1
        [1] => 2.1
    )

[*.2] => Array
    (
        [0] => 1.2
        [1] => 2.2
    )

[*.3] => Array
    (
        [0] => 1.3
        [1] => 2.3
    )

[*.4] => Array
    (
        [0] => 1.4
        [1] => 2.4
    )

[*.5] => Array
    (
        [0] => 1.5
        [1] => 2.5
    )

[*.6] => Array
    (
        [0] => 1.6
        [1] => 2.6
    )

    (
        [0] => 1.7
        [1] => 2.7
    )

    (
        [0] => 1.8
        [1] => 2.8
    )

    (
        [0] => 1.9
        [1] => 2.9
    )

    (
        [0] => 1.10
        [1] => 2.10
    )

    (
