Now all tests work even if Context::context, Context::device, Context::queue are not default context, device and queue. This is required for developing better tests in the future. Note: Some tests may work only for default context/queue/device since classes that they test work only for default context/q/d. There are two solutions for this problem: either those tests run on default queue (no matter what) or they does not run when Context::context is not the default context. See test_string.cpp.
