Link to translated page on locale_switch

[meob-skr]

When I use the locale switch menu, it always opens the homepage of the target language. It would be nice, if Sylius would check, if there is a translation of the Taxon, Product or Page and would directly link to the translated url.

Example:

1. I'm opening the shop's homepage
2. I go to product page xy
3. I use the local switch to get an other language, for example french
4. Actual behaviour: You get the homepage of the (french) language, Expected behaviour: You get the french version of the product xy page.
