QmlDesigner: Don't create module import if later version exists

When creating nodes via 3D view context menu, later versions of
imported modules are also accepted rather than just the exact required
version specified in the ItemLibraryEntry. This fixes the issue of
adding duplicate import statements for the same module with different
versions.
