Subject: Hide button / improve message on missing helpers.

* Emit the `eip_missing_helpers` signal when the user chooses "Don't ask
  me again".
* We emit that signal when some helper file is missing, even if the user
  doesn't want a warning.
* Do the update of the eip enabled status with some delay to give some
  time the eip machine to start and do what it needs with the
  buttons/labels and avoid the 'hide turn on button if missing files'
  being overridden.

Closes #5945.
