Show the first difference when comparing large arrays

[JanTvrdik]

Current result for example:

Failed: array('status' => 'fieldsRequired', 'fields' => array(...)) should be 
    ... array('status' => 'fieldsRequired', 'fields' => array(...)) in testFlowUsCompany()

Expected result for example

Failed: [..., 'fields' => [..., 4 => 'foo', ...]] should be 
    ... [..., 'fields' => [..., 4 => 'bar', ...]] in testFlowUsCompany()

or

Failed: [..., 'fields' =>
            [..., 4 => 'foo', ...]] should be 
        [..., 'fields' =>
            [..., 4 => 'bar', ...]] in testFlowUsCompany()

Another output idea

Failed: ['fields'][4] = 'foo' should be 
        ['fields'][4] = 'bar' in testFlowUsCompany()

This should be easier to implement.

I like the second option with path.
