 Installing a plugin via Ajax fails if `FS_METHOD` isn't defined/set, but
 the UI indicates success.

 Steps to reproduce:
 - Visit http://src.wordpress-develop.dev/wp-admin/plugin-install.php and
 click the "Install Now" button on a plugin.
 - Observe the button change to spinning red arrows, then to green
 checkmark; text changes to "Installed!".
 - Browser network panel shows following response from `admin-ajax.php`:
 {{{
 {"success":true,"data":{"install":"plugin","slug":"theme-check"}}
 }}}

 Trying to activate the same plugin by clicking the "More Details" link and
 the "Install Now" button takes me to the Connection Information screen
 where I'm prompted to enter FTP credentials.

 Adding `define( 'FS_METHOD', 'direct' );` to `wp-config.php` allows the
 Ajax install to complete and the plugin to activate without further
 prompting.
