comprehensiveness_with_validation issues for budget_not_provided about iati-dashboard

[Ocre42]

• Update IATI-Stats/stats/dashboard.py to include budget_not_provided as a separate element to budget in comprehensiveness and comprehensiveness_with_validation
• Update comprehensiveness tests to account for budget_not_provided
• Modify IATI-Dashboard/comprehensiveness.py to obtain the max hierarchy from both budget and budget_not_provided and add up the budget column for both elements.
• Test the changes locally
• Test the changes in a droplet
• Deploy changes in the dev.dashboard, review results
• Deploy changes in live dashboard.

Testing locally with pdb showed that comprehensiveness.py was showing the correct numbers for the budget row, but they were not being saved to the csv or html files, going through further tests.

Droplet test failed due to OOM error, another attempt will be made with the same setup, should this fail again I'll increase the RAM for the droplet.

Saving the budget and budget_not_provided as variables in the generator instead of calling the get methods fixed the issue, ensuring the values are actually saved and copied over to the rows in make_csv and make_html
