Confusing `assertJsonMatches` exception message when arrays are equal but not same

[flohw]

Hello,

I just faced an issue with assertJsonMatches method (note for search engine: which calls json()->assertMatches) can throw a weird exception message : (array:assoc)" to be the same as "(array:assoc)".

It turns out that's because I didn't ordered my array the same way the api endpoint tested returns its.

Value returned by the API:

{
    "errors": {
       "last_name": ["Invalid value"],
       "first_name": ["Invalid value"],
    }
}

Test:

assertJsonMatches('errors', [
    'first_name' => ['Invalid value'],
    'last_name' => ['Invalid value'],
]); // This will throw the exception message above

The same issue applies for multidimensional arrays.

I hope this can be easily fixed. I have no idea how for now. :exploding_head:

Thank you!
