unittests: Remove ATHandler test interdependencies 

Some tests in athandlertest.cpp relied on the state of stubs set in
previous tests. This caused test failures if the tests cases were ran in
isolation. Remove the interdependencies between tests by setting stub
values in the tests that rely on them.
