RelativePath.Parse should fail for invalid namespace index in browse path

[mediawolf]

(checked on commit 2219e02)

I use this overload:
public static RelativePath Parse(string browsePath, ITypeTable typeTree, NamespaceTable currentTable, NamespaceTable targetTable)

browsePath = "2:SomeName"; <-- notice that namespace index is out of range for 'currentTable'
typeTree = session.TypeTree
currentTable = contains two namespaces: 0 - standard OPC UA namespace, 1 - custom namespace
targetTable= session.NamespaceUris which contains four namespaces: 0 - standard OPC UA namespace, 1 - some namespace #1, 2- custom namespace, 3 - some namespace #2

Resulting collection in RelativePath.Elements contains single entry "2:SomeName" which is correct though due to a pure coincidence. I expected a some kind of error to be reported by the method in such cases but, instead, it simply ignores invalid namespace index and keeps original name as is which potentially could point to a completely different node.
