Person gazettes declaring renames of old ministries/portfolios

[sehansi-9]

The problem we encountered was Person type gazettes declaring which old portfolio should be renamed to a newly added portfolio.
For example:

Existing:

• Person A was assigned as Minister of Technology, Technical Education and Employment (a person gazette)

Amendment:

• A new tabular gazette is then released (not an initial tabular gazette) which creates a new ministry as Minister of Science, Technology & Research (an org gazette)
• No org gazette issued to declare that Minister of Technology, Technical Education and Employment has been renamed or terminated.
• Declaring that Person A who had the portfolio Minister of Technology, Technical Education and Employment is renamed to now have the Minister of Science, Technology & Research (a person gazette)

If we track with the Org timeline

• Minister of Technology, Technical Education and Employment (exists)
• Minister of Science, Technology & Research added (new)

both of these exist at the same time, one with a minister, one without (still haven't assigned anyone)- unless we check for similar portions and terminate the previous one simultaneously (add the end date)

If we track with person timeline

• Minister of Technology, Technical Education and Employment - Person A (exists)
• • Minister of Technology, Technical Education and Employment - Person A (terminated)
• Minister of Science, Technology & Research added - Person A (new)

here the person is properly terminated from the previous portfolio

The issue is that if an org gazette isn't released explicitly to declare the renaming/terminating of a ministry, there can be several portfolios with the same domain/ministry at a given point.
