Sites with no courses don't show a link to create new ones. This makes much harder for new teacher/admin users to complete their most basic flow, which is to create a new course. There’s a high risk of them pivoting to other solutions if they are not able to create a course when using Moodle for the first time.

Mockup (outdated – see below):

Acceptance criteria:

For users with capability to create courses as site level on My courses page:

1. There is a link to "Create a new course" if there is no course to show in the main page.
2. There is no link to "Create a new course" if there is at least one course to show.
3. Wether there is any course to show or not, there is a 'New course' link to create a course on the kebab menu

Update

The "My courses" page content is actually the same as the block "Course overview". The follow image illustrate a more realistic version of the mockup above (it's based on the current QA site state):
