FQSEN resolution fails on anonymous classes

[iggyvolz]

When an anonymous class is given to a context, it is unable to resolve the classes of properties in the docblock, even if they are imported.

By removing the error on the given line (phpDocumentor/ReflectionCommon#21), I was able to get it to function; however it was still not resolving the namespace of the property.
