Connect and disconnect without tracker data #5

Closed dtg3 closed 6 years ago

dtg3 commented 6 years ago

Connecting the plugin to the core and then disconnecting without starting the core tracker causes the plugin to hang indefinitely.

Steps to reproduce: 1) Connect to Core 2) Do not hit start tracker on core, and disconnect plugin from Core
