Allow disabling model call on pasting

[GerkinDev]

Hello,

I do a lot of copy/paste from symbols during dev in my own code (like vars names, just because I am extremely lazy), and I noticed that it takes a very long time when continue is on, with an autocomplete model. I'd like to be able to turn off the paste handler only. Would it be possible to add an option for that ? For now, I have to disable all of the completion:

    autocompleteOptions:
      disable: true
