fix: recursive load errors on lib/projects.el

A change upstream was causing recursive load errors. I'm not too clear
how it happens, as I can't reproduce it, but
bbatsov/projectile@3c92d28c056c is the common thread (bumped in
c1b5f48).

Rather than revert the bump, I've just undone the hook and used a saner
hook for the same task. It is a stopgap solution until I eventually
replace projectile with project.el.
