If calling g_subprocess_communicate() on a GSubprocess with no stdout/stderr pipe, a critical warning would be emitted from g_memory_output_stream_steal_as_bytes(), as it would be called on a NULL output stream. Fix that, improve the relevant GIR annotations, and expand the unit tests to cover it (and various other combinations of flags).
