Respect name strategy from WYSIWYG Editor inserted links

It is now possible to create more easily links to page not yet existing from the link modal of the WYSIWYG editor. One option is by typing a link name: the suggester will propose to create a link in current space, or for advanced user it's possible to specify the exact reference and to select the option to create the link with that specific reference. The other option is to create the needed hierarchy from the tree. The links that are created that way will always follow the configured name strategy of the wiki.
