Added functionality for short test caption in CLI

Reasons:
    - Names of tests shown in CLI output are too long to fit the window
      frame size sometimes
Changes:
    - Added functionality that extracts short test description from report
      if test succeded or just its class name and test name otherwise and
      returns as a test name for CLI

Implements blueprint: test-caption
