Adding more unit tests to reach 80% (#177)

* Adding more unit tests to reach 80%

* Adding pmc and command builder tests

* tests for spm, sqtt and trace config

* removing non-existent struct members from test

* Adding logger tests

* aqlprofile_v2 tests

* spm builder tests

* Addressed feedback
