fix: #CO-1815 cant create ticket when go directly on create page

[BastienBenard]

Describe your changes

When you and a teacher arrive on the support home page, you directly open the ticket creation popup. In certain cases this does not allow time for the http request to retrieve the structures to be executed. To resolve this the user will be directly on the ticket list.

Checklist tests

With a teacher account, go to support. We are no longer on the ticket creation page but on the list of tickets.
Create a ticket, the ticket is successfully created.
