fix critical sonar bugs

Restore interrupted state when InterruptedException is thrown in SDNCRestClient
Added test for this case
Replaced formatting anchor with text empty object in GraphInventoryResultWrapper
Escaped anchor is also considered as bug by sonar
Case is already covered in AAIResultWrapperTest
Marked comparison of the same object as false positive in EqualsAndHashCodeTester
Added clearer comment to this comparison
