Previously, Cleanup is scoped to the testing function, which will go out of scope before BackendTest's destructor is called. We need to order the cleanup (destruction of resources) to after the readPixels and previous commands are complete - which is in the destructor of BackendTest. Additionally, we need to cleanup before the destruction of the driver. This means we need to be able to order the destruction of Cleanup (and not rely on RAII). This is done by having a unique_ptr holding a Cleanup instance.
