planemo autoupdate may fail on tools but exit code is 0

Hi,
I noticed it with the autoupdate CI, if you get for example a tool with a problem in the XML like https://github.com/bgruening/galaxytools/tree/master/tools/rna_tools/inforna
When you run planemo autoupdate ., you get in the stderr:

/home/ldelisle/Documents/mygit/galaxytools/tools/rna_tools/inforna/inforna.xml could not be updated - the following error was raised: not well-formed (invalid token): line 38, column 53

And in the stdout:

Auto-updating tool /home/ldelisle/Documents/mygit/galaxytools/tools/rna_tools/inforna/inforna.xml
Could not update /home/ldelisle/Documents/mygit/galaxytools/tools/rna_tools/inforna/inforna.xml due to malformed xml.

But exit code is 0 while I would expect it to be 0.
