Fix creating issue tracker services from templates

What does this MR do?

This merge request fixes two problems when a new project is created and issue trackers templates are active:

1. When there is a property in properties field that is not expected by data_fields (issue_trackers_data or jira_tracker_data) the field is assigned to the data_fields and the process fails (#32544 (closed)). After the fix, only properties that have fields in data_fields are assigned
2. When we create a service from template we don't copy data from data fields. This will be a problem only for new instances but fixed here as it is related.
