ReflectionValueExtractor version with capacity to parse expressions with

…t. The reason is that I've made a mistake and created a unique PR to solve several issues, which is a bad practice.

….4.0-SNAPSHOT

Tests fails because the $HOME env var is no longer defined inside mvn.cmd and is not found (some tests pass even if the env var is not found!).

- Changed the OperatingSystemUtils to allow mocking the Map of env vars.
- Fixed tests to use mocking whenever the env vars are not the focus of the unit test.
- When testing with a REAL env var, it is chosen to be $JAVA_HOME since it is required to be present to run mvn script.
- Added tests to EnvarBasedValueSource and fixed.EnvarBasedValueSource.
