#6487: Mentions.js fails on wp-admin post editor

 When using the post editor in wp-admin, this error is cropping up:
 `TypeError: null is not an object (evaluating
 'window.tinyMCE.activeEditor.contentDocument') on mentions.js:250`

 Console tells me that  `window.tinyMCE.activeEditor` is null.

 In `mentions.js`, I'm reading the following code:

 loadMentionsInTinyMCE = function() {
                         if ( loadAttempts < 4 || ! $( 'body' ).hasClass(
 'wp-admin' ) ) {

                                 if ( typeof window.tinyMCE === 'undefined'
 || window.tinyMCE.activeEditor === null || typeof
 window.tinyMCE.activeEditor === 'undefined' ) {
                                         setTimeout( loadMentionsInTinyMCE,
 500 );

 window.tinyMCE.activeEditor.contentDocument.activeElement )
                                 .atwho( 'setIframe', $( '#content_ifr'
 )[0] )
                                 .bp_mentions( users );

 which, if I understand correctly, it will delay the `.atwho.bp_mentions`
 trigger up to five times for half a second each time, but on the sixth
 time, it's gonna roll anyway.

 I'm adding a patch that only runs if the object's property is set, and
 gives up after the five iterations, but I'm unfamiliar with this
 functionality, so I have some doubts that I really understand what's
 happening here.
