add test that verifies that we can drop the queue before using the device to create a command encoder

[Davidster]

I guess the issue would actually need to be fixed before this test gets merged?

Description
I noticed some code in the wgpu-profiler tests where the queue is dropped before we call Device::create_command_encoder. It produces the following panic:
