Fix: Missing "version" property when writing measure script files

[alexdewar]

As this is a bug, I thought it best to try to merge a fix ASAP so it doesn't get in the way of development.

As @dalonsoa suggested, it would be better if we had a unit test that checks whether the measure script YAML files we're saving are actually valid according to the schema, but I didn't have time to do this properly now, so I've opened an issue: #700.

Fixes #699.
