Fix errors issues

[stefanbotez]

Description of changes:

• Fixed issue when if statement was checking for ExtendedError, but it should have checked for Error. That if statement was never passed, so the logs of the error were not complete.
• Added a test for the above fix. Before there was a test that checked the logging error behavior, but it checked with a CircularError, which was only testing the case when the try statement failed. Added a test that would test the behavior for when the try statement succeeds (i.e. testing the _withEnumerableProperties method).
• When facing a SyntaxError only the message of the error would get logged. Changed it so that the whole error would get logged.
