INDI Devices Handling Refactor

Previously I could add a keyboard shortcut bound to Slew to Mouse Pointer, then move connect Indi/Ekos, then put mouse over SkyMap, and type the shortcut and the (simulated) telescope would slew to the position of the mouse. After the above commit, this no longer works.

I git bisected and found that the functionality works fine on the previous commit, but is broken after the above commit.
