Refactor and consolidate IParameterExpression

[JSkimming]

Problem

There are two near identical implementations for retrieving injected dependencies, originally constructor dependencies, and lateley property dependecies.

The logic in both implementations encapsulates:

• Finding the composition for a dependency.
• Handling IEnumerable<> dependencies.
• Throwing a CompositionException for missing dependencies.

I'm not sure a third implementation could arise, (though it's possible), but it's likely a broader set of collections add amplified types will be supported, e.g. arrays, List<>, IReadOnlyCollection<>, Func<>, Lazy<T> etc. Therefore consolidating this into a single implementation would be beneficial and DRY.

Proposal

Not sure yet, most likely an internal static helper method.
