fix(multiple-cursors): contextually activate minor mode

Browse source 
evil-mc's design is bizarre. Its variables and hooks are lazy loaded
rather than declared at top-level, some hooks aren't defined or
documented, it's a bit initializer-function drunk, and its minor modes
are intended to be perpetually active -- even when no cursors are active
(causing #6021). I undo all of that here.

Fix: #6021
