Refactor only the links of the translations that actually have a link to the moved page

Currently, whenever a page is moved, if only one translation of a document has a link to the moved page, all the translations are refactored (see https://github.com/xwiki/xwiki-platform/blob/886b1cdde49d84c1a52f204a65782aae4eccdb86/xwiki-platform-core/xwiki-platform-refactoring/xwiki-platform-refactoring-default/src/main/java/org/xwiki/refactoring/internal/DefaultLinkRefactoring.java#L139).

Now that we index the document ids in the backlinks, it is possible to be more selective and to only refactor the translations that actually have a link to the moved page.
