Fix issue with non breaking space after delimiter

[jpopesculian]

Autocomplete can jump to the beginning of a node if there's a non breaking space after the delimiter when typing:

TinyMCE content:

<p>Hello my name is&nbsp;!</p>

If you were to type

<p>Hello my name is @&nbsp;!</p>

The autocomplete would fire and your cursor would select the beginning of the paragraph. The solution is just to reference the delimiter id when reselecting

Thx, I will have a look why the tests are failing.

Hi, I cannot really reproduce this issue...

The element you are selecting in the dom does not even exist? 'span#autocomplete-searchtext span#autocomplete-delimiter'
