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
