Support results being copied even when commands have been added or removed between versions

[howard-e]

This PR updates processCopiedReports.js to account for when commands have been added/removed between versions.

Previously, if a test had a command be included or removed in a subsequent update, all assertion results, unexpected behaviors and output would be discarded during the copy process.

Addresses the following from #935:

1. Need to account for when commands have been added, removed or edited for a test
2. Unmark test plan reports as final once the results have been copied into a new TestPlanVersion's TestPlanReports to make it clearer that the results have been successfully copied. Test administrators will be able to make changes and mark as final again, if appropriate.
3. Functionality to support copying results when a TestPlanVersion is in an advanced phase.
4. Need to be able to pull older results when also adding an individual Test Plan Report to the Test Queue instead instead of just providing that functionality during the advance process from the Data Management page

2, 3 and 4 have been individually reviewed in separate PRs through:

• Unmarks newly copied test plan reports as final during results copy process #974
• Copy results from advanced phase #976
• Copy results when adding to Test Queue #978

I did highlight one change, but it was something insignificant in a comment, so I removed the suggestion. The changes here are working fine, and the code seems good to me. Good stuff, as always.
