Remove old/outdated Tests and Fix failing Tests

[PrashantVaidyanathan]

Currently, mvn verify fails. This is quite confusing for users who are installing/using Clotho for the first time.
The following needs to be done:

• Look at all the tests in the Test package. Remove all outdated tests.

• If a test is relevant but failing, fix it. (Create an issue and assign it to the concerned dev)

• Ensure that mvn verify returns "Success".

• Check the logger and comment out cumbersome and unwanted 'text' while compiling.

Once this is done, #506 should be tackled.
