editeng: change EditEngine getter to ref in {Imp}EditView

{Imp}EditView always needs to have EditEngine set (or it would
crash otherwise), so we can change the getter to return a referece
instead of a pointer. This simplifies things a bit because we get
rid of all the nullptr checks and makes the interface more clear.

Also change direct access to mpEditEngine in {Imp}EditView to use
getEditEngine() and getImpEditEngine() (returning a reference)
instead.
