require.main is undefined when running from cli - don't use unless it exists
- This require introducing a way of having "require.main" undefined in our module. The require function is different between the test module and the module under test, so we can't just do `require.main = null` in the test function, as it won't affect the "require" function of the prod code. So we need to introduce a helper function for evaluating require.main, and injact a flag in the test module when running the tests.

Fixes #65
It builds on top of @dgobaud's PR, and adds tests.
There might be some rare cases when you want to use module-alias while running in a REPL (e.g.
$ node -i). In that case,require.mainis undefined.This means introducing a way of having "require.main" undefined in our module. The require function is different between the test module and the module under test, so we can't just do
require.main = nullin the test function, as it won't affect the "require" function of the prod code. So we need to introduce a helper function for evaluating require.main, and inject a flag in the test module when running the tests.
