bitbake: toaster/tests/functional: Improve project creation tests

Mixing database access and access via a running server is fraught with
danger and problems. The "django_db" marker means the transactions are
dropped at the end of the test but the transactions made via the webapi
remain so the database ends up confused at best.

Drop the database accesses and use the server API. This means slightly
abusing the typeahead to get lists of projects in the database.

Add code to delete a project if it already exists. This allows tests
to re-run against an existing database. Deletion is done using the
server API but this means handling CSRF tokens.

Add requests module requirement to requirements file since the project
creation code now uses requests.
