NeoVim config improvements

* Removed auto-pairs plugin - it only causes difficulties
* Fixed OSC52 yank - no more crashing on "y" key press
* Added abbreviation for binding.pry that I use a lot

Also yet another attempt to fix OSC52 In mosh-tmux environment.
Unfortunately mosh project is abandoned, so there is no chance
mobile-shell/mosh#1054 will be merged.
And those workarounds actually never work.
