#48786: Wrong URLs to categories, authors etc. to a site in a multisite

--------------------------+-----------------------------
 WP returns a wrong URL to a term if the term is in another site of a
 multisite. Terms like categories, tags, authors, date archives and other
 terms.

 How to reproduce: execute this code, with site ID and post ID as examples
 of valid values in the current installation, in a subsite different to
 site ID = 3:
 {{{#!php
 <?php
 $site_id = 3;
 $post_id = 1389;
 $category_links = array();

 switch_to_blog( $site_id );
 $categories = get_the_terms( $post_id, 'category' );
 foreach ( $categories as $category ) {
         // get link to category
         $category_links[] = sprintf(
                 '<a href="%s">%s</a>',
                 esc_url( get_category_link( $category->term_id ) ),
                 esc_html( $category->name )
         );
 }
 print join( ', ', $category_links );
 restore_current_blog();
 }}}

 If other base names for the category and tags are used (being specified on
 the Permalinks Settings page) the bug is more obviuos. In the next example
 the subsite is the german version of the main site, so the site path is
 '/de' and the category base name is specified to 'kategorien', and the
 german name for the category 'General' is 'Allgemein':

 On the english main site the code prints this URL to the german category
 'Allgemein':
 {{{https://www.example.com/de/blog/category/allgemein/}}}
 which is wrong. The correct URL is
 {{{https://www.example.com/de/kategorie/allgemein/}}}

 On the german subsite the code prints this URL to the english category
 'General':
 {{{https://www.example.com/kategorie/general/}}}
 which is wrong. The correct URL is
 {{{https://www.example.com/blog/category/general/}}}

 The code sets correct links if it is executed in the site with the ID = 3
 (e.g. is current site is same as the site being switched to).

 Same is with similar functions like:
 {{{
 get_author_posts_url()
 get_category_link()
 get_month_link()
 get_post_format_link()
 get_post_type_archive_link()
 get_tag_link()
 }}}
