 In a WordPress multisite installation, when you try to import an XML file,
 from a sub-site, you will be provided with an invalid link to the "'''Run
 importer'''" page after the installation of the "WordPress Importer"
 plugin. This bug will not be there if it is not a multisite website or if
 the "WordPress Importer" plugin is already installed.

 Steps to reproduce:

 1) Create a Multisite website.
 2) Go to one of your sub-sites.
 3) Make sure that the "WordPress Importer" plugin is '''not installed'''
 already (https://wordpress.org/plugins/wordpress-importer/).
 4) Go to Import section in Tools menu.
 5) Click on "Install Now" under WordPress import section.
 6) Now the WordPress Importer plugin will be installed though ajax
 request.
 7) After successful installation, "Install Now" link will be replaced with
 "Run importer" link and also, you will be provided with a message at the
 top - "Importer installed successfully. Run importer".
 8) Expected result is a proper, working link to the importer page., inside
 the current sub-site. But you can see, since the Multisite plugins are
 managed from network dashboard, the link returned through the ajax
 response is invalid, as "/network" is appended in the plugin's link.
 9)
    a) Expected link : mysubsite1/wp-
 admin/plugins.php?action=activate&plugin=wordpress-importer%2Fwordpress-
 importer.php&from=import&_wpnonce=123nonce

    b) Current link : mysubsite1/wp-
 admin/'''network'''/plugins.php?action=activate&plugin=wordpress-importer
 %2Fwordpress-importer.php&from=import&_wpnonce=123nonce

 10) This results a 404 error when we click on '''Run mporter'''.

 Please see the screenshot.
