Remove addModules( 'ext.uls.init' )

The modules 'ext.uls.init'/'ext.uls.common' provides only a library and
no own funtionality. The modules get automatically loaded through
dependencies by other modules when needed as library. An explicit
loading on all page is not necessary. For example the MediaWiki API
help page does not have any ULS elements.
