WIP: Find why travis fails on delete journal through edit & restore the test

Story in Trello

The test in journals_test.rb:

  test 'can_delete_a_journal_through_edit' do
    Journal.with_deleted.map(&:really_destroy!)
    create :journal, journalable: @volunteer
    visit volunteer_path(@volunteer)

    click_button 'Journal'
    within '#journalBlock' do
      click_link 'Edit'
    end
    page.find('a', text: 'Delete').click
    assert page.has_text? 'Journal was successfully deleted.'
    click_button 'Journal'
    refute page.has_link? @journal_volunteer.user.full_name
    refute page.has_text? @journal_volunteer.body
  end

Test result locally:
