[Bug] - tresury report does not generate if projects in all three project-types do not exist

[as1729]

Current State

If the organization only has either 1A, 1B, or 1C or missing any of these project types, then the treasury report raises the following error.

Expected State

The treasury report generation should not raise any errors if the organization only has one type of project. It should merely put a log indicating that the organization does not have any uploads with the specific project type.
