Fixed sonar issues
Refactored overcomplicated methods by splitting into the more simple. Remove redundant conditional checks. Move common checks into the utils class. Fixed raw types usage where it is possible. Add some tests. Fixed typos in test names. Fixed lost switch branch. Issue-ID: SDC-2698 Signed-off-by: Dmitry Puzikov <d.puzikov2@partner.samsung.com> Change-Id: Ifb5887401be4b397267b2f922cc9ad3f01c757f6
