Add new test cases for security-server password API.

Add new test cases for security-server password API.

[Issue#]       SSDWSSP-707
[Feature/Buf]  New test case.
[Cause]        Checking cases not considered before.
[Solution]     Added a test checking if security-server behaves as required.
               Test tc41_security_server_empty_history_check was reworked in
               SSDWSSP-708 to check reusing password after limiting history
               because, although technically a part of this issue, it was
               necessary for the whole testsuite to pass.
[Verification] Build, install, run tests.
