SM: TestSecurityManagerDatabase class removed
- most checks implemented using security_manager_get_app_pkgid()
- checks whether package has been removed after app uninstall removed
- privileges test in security_manager_02_app_install_uninstall_full
implemented using policy privileges (no need to inject priv:group)
- get_author_id() function has no counterpart currently
- some changes in the PolicyConfiguration class to add functionality
required by the tests now
