Description

We have the context URL $metadata#A(1)/b(1)/c(1)/d where A is an entity set and b, c and d are containment navigation properties.

Parsing this with org.apache.olingo.commons.api.data.ContextURL results in:
entitySetOrSingletonOrType = A/b/c
navOrPropertyPath = c(1)

The result should be (at least what is expected but which might not be correct, see below*):
entitySetOrSingletonOrType = A/b/c
navOrPropertyPath = d

This results in ODataBinderImpl finding the incorrect type for the returned entities.

*Depending on your point of view
entitySetOrSingletonOrType = A
navOrPropertyPath = b(1)/c(1)/d

or

entitySetOrSingletonOrType = A(1)/b(1)/c(1)/d
navOrPropertyPath =

might be what you would expect as a result of the parsing but the current code wouldn't be able to handle such results.
