Move the source code position for classes to the point where the block context has already been created. Previously, there would be a mismatch between the context and the scope when using the ScopeIterator. We paused at a point where, according to the source position, we already are in a class scope, but according to the bytecode (context), we would not yet have created the block context for the class.
