Refactor completion/ivy & optimize projectile-find-file

Browse source 
counsel-projectile-find-file fontifies visited files and sorts the
resulting file list from projectile-find-file, adding considerable
overhead. Then, ivy-prescient performs a frecency sort and filter,
adding more overhead.

Altogether, this makes projectile-find-file unusable for larger projects
when fuzzy search is on (and in some extreme cases, when it's off). This
change disables both features specifically for projectile-find-file.

Fixes #774, hopefully
