assertEquals() compares objects by comparing each property for both
objects. This was done by using Object.keys() which however only returns
enumerable properties.
With this change also non-enumerable properties are compared.
Still, the comparison doesn't require the properties to be equal.
So, if one property is marked enumerable in one object but not the
other, the objects would still be considered equal.
This could be adapted in a follow-up CL if desired.
The prototype is still ignored for the comparison.
