Tomasz Zawadzki 86278ab90e unit_test: check for adding same lun twice to scsi device
This patch adds two new unit tests for scsi device:
- creating two different devices, each containing the same lun
- creating one device, with the same lun twice

As noted in code, three asserts are incorrectly set to show functionality
that is not working currently.
Next patch in series implements that functionality and changes asserts
in the unit tests.
