Annotator users can't annotate data (django exception TemplateDoesNotExist)

[mdumitru]

How to reproduce the behaviour

1. Install and run doccano through the "Docker Compose" workflow on github.
2. Create a new user "test".
3. Create a new "DocumentClassification" project.
4. Import a dataset.
5. Add user "test" as a member of the current project, with the role set to "Annotator".
6. Login as user "test" and select the previously mentioned project.

The "admin" user can see the dataset in the "dataset" tab and can use "Start Annotation" to annotate the dataset. However, the "test" user does not see anything in the "dataset" tab; similarly, clicking on "Start Annotation

In the terminal from which doccano was launched the following output appears:
