IdStory Identity Manager

Problem occured because final delete of the account was executed twice. First by deleting the relations between entity and account. Second by directly delete of the account.
This problem not occured for identity entity type, because only identity type supports "Protection mode". For this is uses another delete way.

• I fixed this (https://github.com/bcvsolutions/CzechIdMng/commit/c944d1df031a6ef98aefb5fbca1f4b1b2ade9993).
• I created test for dirctly delete of non identity account.
