While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
* Fix Unintential Deprecated Calls in Tests - DATABASE
I think it's best to install these before PR #3166. There are no changes to source code, only to test members which continue to inadvertently use calls to deprecated functions.
* Fix deprecation Blocks
Deprecated->deprecated, adjust see and comments
* Fix Deliberate Deprecated Tests
Add annotations.
* Change Unit Tests to Run in Spreadsheet Context
... rather than as direct calls. The major difference is that specifying an invalid column should result in an Excel error, not null. Minor code changes were needed, including to Statistical/Conditional which sometimes calls Database.
* Correct Some DocBlocks
Null is no longer a possible output for most of these functions.
* 2 Overlooked Tests
Change to run in spreadsheet context.
* T Function Should Return Null-String, not Null
Fix it.
