[FIX] test_base_automation: fix failing tour

This commit fixes a tour that is failing undeterministically.

- Before
  The tour was saving a form dialog just before saving the main form.
  Sometimes, these two steps were too fast, leading for the second one
  not performing the main form save action.

- After
  The second step now awaits that the modal is closed before running.
  This element is the kanban record saved by the form dialog.

Fixes runbot error 24576
