ServiceList Does Not Preserve Keys

[XedinUnknown]

The ServiceList class is very useful for combining several services into a list. One of its useful abilities is to map them to keys that have meaning, rather than just the numeric index in the service definition list.

Unfortunatley, the mapping doesn't seem to work: it uses the olde resolveDeps(), despite useing the ResolveKeysCapableTrait.

Moreover, ResolveKeysCapableTrait#resolveKeys(), which should presulably be used to preserve the keys, uses resolveDeps() directly, without changing anything. And that, as we know, does not preserve keys.

Suggested Solution

It seems that the ResolveKeysCapableTrait was added in order to distinguish between key-knowing and key-agnostic resolution. Probably, just forgot to change ResolveKeysCapableTrait::resolveDeps() to use the key rather than [] (push).

I don't think we forgot to update resolveDeps(). Rather, I think we forgot to update ServiceList.
