<pre>Description:
Python module uno.py overrides import. And that overwritten function fails to
import some modules. Cairosvg is one example.
Workaround is to import carirosvg before libreoffice ones.
It looks like sys.modules can contain entry for module with value None. Maybe
simple check against that would work. Or maybe there is needed other approach
with Python 3.8?
Steps to Reproduce:
Simle code like:
import uno
import cairosvg
After failure it looks like sys.modules["_elementtree"] is None.
(Key exists in that dict, but with None as value)
Actual Results:
Traceback (most recent call last):

Expected Results:
Proper import of cairosvg, with modules it imports.
Workaround is to use:
import cairosvg
import uno
Reproducible: Always
User Profile Reset: Yes
