Undo should not undo each suggested word and typed character

[alexchee]

Atom's change to the way it handles undo history, broke this line: https://github.com/alexchee/atom-inline-autocomplete/blob/master/lib/inline-autocomplete.coffee#L91
selection.insertText(match.word, { select: false, undo: 'skip' })

Need to figure out a way to get the undo history to at least only do it for the previously typed word and not leave the extra suggested text behind.

Maybe there's a hook to undo or another method to replace text that will make undo behave this way.
