Description

In an extension, if there is a new data type B:
data_type_def: B
data_type_inc: A

And type A has attributes, e.g., 'description', and B does not override those attributes, then those attributes should not be included in the __fields__ generated by get_class. Currently, they are duplicated in the child class. A recent change in HDMF raises an error if this occurs.

This is due to a bug in BaseStorageSpec.resolve_spec where attributes are not correctly removed from the set of new attributes.

The recent change that raises an error should instead raise a warning.
