Cannot use cached namespaces from NWB file instead of default

[gouwens]

Description

At the Allen Institute, we have some NWB2 files that can't be read by the latest versions of pynwb because of a namespace problem. These NWB files use the "Index" data type which was removed in hdmf-common version 1.2.0.

When I try to load the file, it ignores the hdmf-common namespace version 1.1.3 cached in the file (which still has the "Index" type) because it has already loaded version 1.5.0 (I think just automatically because of the global namespace catalog?). There doesn't seem to be any way of overriding that default, so loading fails because "Index" is not specified in version 1.5.0.

Steps to Reproduce

import pynwb
nwb_path = "Ctgf-T2A-dgCre;Ai14-533670.04.02.02.nwb"
dataset = pynwb.NWBHDF5IO(nwb_path, mode='r', load_namespaces=True)

/local1/anaconda3/envs/py3/lib/python3.7/site-packages/hdmf/spec/namespace.py:533: UserWarning: Ignoring cached namespace 'hdmf-common' version 1.1.3 because version 1.5.0 is already loaded.
  % (ns['name'], ns['version'], self.__namespaces.get(ns['name'])['version']))

Sure thing. I've attached an example file in a ZIP archive.

I'm running into this too, now affecting validating files for upload to DANDI. seems like it's maybe also related to #1289 ?
