cptMetrics - improve Staffing Profile - use Resume instead of subtracting actuals

[AronGahagan]

Problem:

If a user clears out actual work in the past (or has ActiveProject.AutoCalcCosts = False then data could be incorrect.

Solution:

Use Resume (or Status Date) as the start date for Work instead of getting all work and then subtracting Actual Work instead.

Todo:

• assign this issue
• label the issue for enhancement or bug
• label the issue with codemodule (so fixes can be aggregated and hotfixed together)
• checkout appropriate branch and create topic branch
• design, code and test
• update codemodule <cpt_version>x.y.z</cpt_version>
• update CurrentVersions.xml manually
• commit changes prefix comment with Issue #XXX -
• merge topic into appropriate branch(es) and push
• delete topic branch

...it's possible this was already fixed, and the vestigial subtraction code to subtract actuals isn't cough actually subtracting anything. The current code defaults to using Resume as the StartDate for TSVS if the task has an Actual Start (and no Actual Finish).
