Nerves.Network.teardown/1 not disconnecting from wireless network

Running on a Raspberry Pi Zero W and connecting to an iPhone 7 personal hotspot, calling Nerves.Network.teardown "wlan0" removes the network configuration from the SystemRegistry, but the network remains up. I added in HTTPoison and confirmed that I could successfully make network calls after tearing down the interface.

This issue is sort of a duplicate of #22 and #26
I'm going to leave it open, but they will likely both be taken care of at the same time.

ConnorRigby commented

Should be fixed in #97 but another PR is open #98 to finalize this.
