QmlDesigner: Fix lookup of navigator icons

The version check was simply wrong.
The version of the used item might be higher then the version in the
item library. We can still use the icon.

I removed the version check completely. There is no reason to have different
icons for different versions. This just increases the complexity and
introduces bugs without any reason/use cases.
