When learning a structure type and the corresponding structures of its fields using UaStructureDefinition.FromTypeNodeId(), an unexpected error occurs when reading the structure fails on a field which has AllowSubTypes set to true in the corresponding place in the 'overrideTypeTree' argument. The function should return false when reading of a structure fails at any point, instead of processing an empty returned value.

Furthermore, the log information about which field structure is being processed next, should be printed to make it easier to localize the issue if an error occurs.
