Feature/229 more test cases

[felix-zailskas]

Added test cases for:

• Analyze Email Step
• Hash Generator Step
• Preprocess Phonenumbers Step
• Console Utils
• Pipeline Utils

The test coverage is now at 45%. This is due to newly added code in the last week. I added tests for all modules that were easily testable with straightforward unit tests. The effort, complexity and time required to test the other modules seems to exceed the scope of this sprint, hence I will not implement them. The desired coverage of 60% is not realistic.
