Truffle/Testing: massive rework of tests to accommodate recent instrumentation change with respect to "applyInstrumentation"
- Caused by lack of a "vm" known to the Accessor during most testing, making the Instrumenter unavailable, which is now required to create a CallTarget
- Modified the Instrumenter/Accessor with a static field that can be reflectively "poked" with a vm value for testing
- Create a pair of methods to globally enable/disable testing mode to modify that static field and restore it when tests complete.
