refs kylelutz/compute#9 device, context, and queue are initialized statically in `context_setup.hpp`. With this change all tests are able to complete when an NVIDIA GPU is in exclusive compute mode. Side effect of the change: Time for all tests to complete reduced from 15.71 to 13.03 sec Tesla C2075.
