[Bug] Broken running status

[benlubas]

#69 broke the "running" status

@usmcamp0811 I have some questions about this PR that you submitted

here you set self.external_kernel to true in both cases, and then you gate the "running" status update behind not self.external_kernel here. This just completely disables the running status functionality.

I'm assuming that in this case if ".json" not in self.kernel_name: it's supposed to set external kernel to false, and that line is just a typo. But I'm also wondering why the status updates needed to be disabled with external kernels at all?

I'll note for completeness that this also removes magma's ability to shut down a running kernel on deinit. as seen here
