Timo Tijhof 76245d70ff resourceloader: Add integration test for ResourceModuleSkinStyles
This was covered in small ways already, but we did not have coverage
of the registration logic where the skin attribute is injected into
the module info, and this then correctly getting read and composed
into a single stylesheet.

This is prep for an optimisation in a subsequent commit.
