Error when deactivating package

[lexicalunit]

Occurs for me every time the package gets deactivated. Only tested in Atom 1.16.0 beta so far.

I believe detach() should be called instead of dispose(). From a cursory review I don't see dispose() defined for a View object. It's also worth noting here that space-pen and atom-space-pen-view are deprecated and will soon be removed from Atom entirely. It would probably be worthwhile to refactor the codebase to use manual DOM manipulation before Atom 1.16.0 is released.
