[Editor] Avoid to update default params too early

[calixteman]

I got this exception in nightly:

Uncaught TypeError: can't access property Symbol.iterator, this[#editorTypes] is null
    updateParams resource://pdf.js/build/pdf.js:4393
    set annotationEditorParams resource://pdf.js/web/viewer.js:11521

    dispatch resource://pdf.js/web/viewer.js:4133
    bindListeners resource://pdf.js/web/viewer.js:4496

I don't know how to reproduce the issue.

I don't know how to reproduce the issue.

I only managed to reproduce this by having a PDF document open when applying a Nightly-update, and could then see those Errors in the console when the browser had restarted after doing the update.
However I've not been able to reproduce this in any other way, e.g. by manually re-starting the browser, so hopefully this isn't a common problem. I'm also slightly confused as to how that problem even happens though!
