Import broken for use of workflow tags

Current Situation

• With release 2.7.2 grouping of tags was introduced.
• When exporting workflows that hold tags then the workflow.tags.json file is created in the root of the export archive file.
• The file contains available workflow tags but no related grouping information. As a result the import of the archive file fails if workflow tags are included in workflow.tags.json as the tags cannot be imported due to missing grouping information.

Desired Behavior

• Add grouping information for workflow tags to the workflow.tags.json file. Groups are specified by using <group>:<tag> for related tags in the workflow.tags.json file.
• Consider grouping information on import of workflow tags.

Workaround

• Users can remove the workflow.tags.json file from the export archive file before import.
