[Bug] XML - testing an element's truth value will always return True in future versions #5756
Description
Describe the bug
Testing an XML element's truth value will always return True in future versions. This would cause issues once the new behaviour will be turned on. We should be prepared and avoid this unexpected behaviour in places where it is in use.
To reproduce
> g.extension i.modis op=remove -f
/home/ondrej/workspace/grass/dist.x86_64-pc-linux-gnu/scripts/g.extension:2149: DeprecationWarning: Testing an element's truth value will always return True in future versions. Use specific 'len(elem)' or 'elem is not None' test instead.
