Use absolute paths when building entry classes

[joshuap]

When using nested expands, inline entries can contain deeply nested
properties and inline elements of their own. Rather than performing a
match on any node under the current, select only the first level
properties or inline entries nodes.

The bug I was having is this (arbitrary example):

svc = OData::Service.new('...')
svc.Products.expand('Categories').expand('Categories/Sections')
products = svc.execute

products.Categories would contain both Category and Section classes, since it was matching every nested entry rather than just the first level for each Product entry node. Also, properties were not being set on the first expand associations - so products.first.categories.first.ID would be nil, even though the properties element was present for that category.

Could you create a test specifically for this issue. If you look at the test suite, I've used the VCR gem to capture responses and then load them into my tests (so we can test offline).

That is for Cucumber features. However, it's easier to just grab the XML response of the metadata from the service as well as the results of a specific query that gave you the problem, then add RSpec tests using that data. Here's an example: f5b30d8

I was able to reproduce the problem using the public Northwind OData service, thus I was able to add tests for the issue.

This has been merged into the develop branch. Thanks for the fix!
