This patch simply checks if conditionals are defined before comparing
We don't need to check actions because you cannot save an action without an action :-)
To test:
1 - Define several actions for a MARC modification template
2 - Ensure you have actions with no conditionals
3 - Tail the intranet logs
4 - Browse to Tools->MARC modification templates
5 - Click 'Edit actions' for the template you setup above
6 - Note warns like:
[2020/10/22 12:30:18] [WARN] Use of uninitialized value in string eq at /kohadevbox/koha/tools/marc_modification_templates.pl line 127.
7 - Apply patch
8 - Restart all the things
9 - Edit actions again and note no more warns
