Not generating URLs with "limitstart=0"

Instead of removing the "limitstart" parameter in the router file (see https://github.com/joomla/joomla-cms/pull/3725 ), we do not generate URLs with "limitstart=0".
Kind of weird to add it there to be then removed in the router, isn't it?

So components will be able to use the parameter "limitstart=0" if they want to... and we still avoid the duplicate url issue we used to have.
Sounds like a win / win! :)
