Remove random key from comment field

[norbye]

Description

Removes the wait introduced in #4176

CommentFields were set to have a random key (why I do not know), that would make it re-render excessively (and thus clear the focus and content of the new comment). This removes the key, and rather handles form resetting by using the form.change() method.

Changes done to TextInput.ts were done to avoid bugs that were discovered while trying another approach.

• When inputRef was used as a parameter in useRef(), it did not update inputRef when newInputRef was used. Thus it was not possible to pass a ref through to the component.
• Small typescript errors

Result

When run on my machine this works quite well, and I can start writing comments before all the content of the page has been loaded - which was not the case previously.

To see if this resolves the cypress-bug, we'll probably have to wait and see. This passed cypress on the first attempt, but lately it has worked some times and some times not, so it's no guarantee.

Testing

• I have thoroughly tested my changes.

Have been testing that the comment form works as expected in the event view.
