envs in if: - take 2 (#412)

* Test more if env variants

* The correct negation syntax is !=

* Make the Interpolate function support negated booleans from envs

* Move assert := a.New(t) into t.Run

This uncovered that some of the test premisses was wrong and the
Eval Bool function also had flaws

* Remove a stray logrus import
