RSRP-329678: Situation is very rarely possible when "create" quick fix is not suggested and user sees only "add argument name" until she moves the caret

Very minor issue which prevented one of integration tests from pass in 7.1.
In 7.0.1 it was ok.

Code to type:

     public void Add<T> (T obj)
     {
         using (Mongo mongo = Mongo.Create())
         {
             
         }
     }   

Move caret after "Create()", wait for a while, then move in between "Create(" and ")", immediately type "c", wait for intellisense suggest to appear, press [Esc] and call quick fix. Only "add argument name" quick fix is suggested (see minor.png). If I move the caret back and forth, "create" submenu is displayed (see minor2.png).

Minor, but issue. Users who type non-one-symbol variable names or one-symbol names which do not lead to intellisense suggestion and who are not robots won't ever notice it. :)

To sum up: if there is "create" fix available for one-letter or very-very-quickly-typed variable, but intellisense menu was shown and hidden by [Esc], "create" fix will not be shown.
