fix flickering PDFs in pdf-view-mode

[mnick]

Zooming into PDFs in PDFView conflicts with blinking cursors in evil-mode what causes the PDFs to flicker.

This applies the fix from politza/pdf-tools#201 what resolves the issue for me.

Sorry for the late response. Is there any reason we can't simply set evil-normal-state-cursor in this case? e.g.

-(set-evil-initial-state! 'pdf-view-mode 'emacs)
 (add-hook 'pdf-view-mode-hook
           (lambda ()
-            (set (make-local-variable 'evil-emacs-state-cursor) (list nil))))
+            (set (make-local-variable 'evil-normal-state-cursor) (list nil))))

evil-collection provides some evil integration for the pdf major modes. I'd like to preserve them, if possible.

Side note, setq-hook! may be more convenient here:

(setq-hook! 'pdf-view-mode-hook evil-normal-state-cursor (list nil))

As of 36a97b2, the alternative I suggested above is now in develop. Thanks for your help and for bringing this to my attention!
