Remove uncaught_exception uses in tests

Remove uncaught_exception uses in tests

[Bug/Feature]   uncaught_exception is bugged since 2008 and can return a false
                result on some specific situations (refer to
                https://gcc.gnu.org/bugzilla/show_bug.cgi?id=37477 for more
                info).
                Some tests (especially Cynara Agent) relied on uncaught_exception,
                which when failed resulted in double-throwing. This caused instant
                test termination and emitted SIGABRT.
[Solution]      Remove uncaught_exception calls, reorganize some test parts to
                avoid throws propagating outside destructors.
                Additionally, minor corrections to boilerplates (copyright date)
                were made.
[Verification]  Build, install, run tests several times on mobile image. The
                tests should not receive SIGABRT during Cynara Agent tests.
                Test results should be unaltered (some of the tests fail due
                to timeouts).
