The javadocs of the CharSequence interface state that not all of its
implementations define the general contracts of the Object#equals and
Object#hashCode methods, therefore it is dangerous to use different CharSequence
instances as elements in a set or as keys in a map.
While we probably mostly use Strings in those sets, in some places this is not enforced.
To prevent this from accidentally happening, this change replaces all occurances of
Set which are currently mostly used in the completion suggester code
with the more concrete usage of Set.
