No error validation for ticket type

[anchovy]

Describe the bug

If you add a ticket by don't select a ticket type an Twig\Error\RuntimeError is thrown rather than a form error in line i.e. no price added.

Steps to reproduce

1. Add/Edit an event

2. Goto the tickets tab

3. Click 'Add Ticket'

4. Enter a price but don't select a ticket type

5. Save the form

6. A Error is thrown:

   
   Twig Runtime Error – [Twig\Error\RuntimeError]
   Impossible to invoke a method ("getFieldLayout") on a null variable.

7. in /....../vendor/verbb/events/src/templates/_includes/ticket-row.htmlat line 97 instructions: 'Tickets will not be purchasable after this date.' | t('events'), id: 'availableTo', name: 'availableTo', value: ticket.availableTo ?? [], errors: ticket ? ticket.getErrors('availableTo'), }) }}

       <div class="ticket-type-fields">
           {% if ticket %}
               {% for tab in ticket.type.getFieldLayout().getTabs() %}
                   {% include '_includes/fields' with {
                       fields: tab.getFields(),
                       element: ticket,
                   } only %}
               {% endfor %}
           {% endif %}
       </div>
   </div>

Fixed for the next release. To get the fix early, change your verbb/events requirement in composer.json to:

"require": {
  "verbb/events": "dev-craft-3 as 1.4.23",
  "...": "..."
}

Then run composer update.
