excludeBundle error - Array to string conversion

[cluwong]

Trying to use excludeBundles property, but when the css item is in array format, it runs into exception error 'Array to string conversion'.
eg:

$css = [
    ['style.css', 'id' => 'myStyle'],
];

In 1.15.1, error is in MinifyComponent.php line 105.
I just realized there's V2, tested with this version and the error is in MinifyComponent.php line 112.
