lava: Stop pointing to dropped testcases

Commit 822fb8b8 dropped a few testcases, but the profiles still
point to them, resulting in errors like on
https://lava.collabora.co.uk/scheduler/job/2572900

:

    Job error: Unable to open test definition 'test-cases/tracker-indexing-local-storage.yaml':
    [Errno 2] No such file or directory:
    '/var/lib/lava/dispatcher/tmp/2572900/lava-overlay-knf8ynqa/var/lib/lava-2572900/2/tests/21_tracker-indexing-local-storage/test-cases/tracker-indexing-local-storage.yaml'
