[scope] [Dependency] Don't annotate constructor parameter with scope
[scope] [Dependency] Don't annotate constructor parameter with scope

When the `in` parameter storage class changes its meaning to `scope const` we would get
the following errors:

source/dub/dependency.d(83): Error: scope variable `ver` assigned to `this` with longer lifetime
source/dub/dependency.d(84): Error: scope variable `ver` assigned to `this` with longer lifetime

This commit fixes this.
