Make a missing --sets-mode property for a key binding do nothing

Browse source 
Currently, if bind is run with --mode but not --sets-mode, the
binding gets an implicit --sets-mode equivalent to the mode. This
is usually unobservable but it may matter if the mode is changed
by some internal part of the binding (e.g. set fish_bind_mode...)
then that setting will be lost after the binding is complete.
