[Tarantool-patches] [PATCH] box: user.grant error should be versatile

[Alexander Turenko]

We can just revoke privileges granted for 'guest' and the patch will be
smaller.

Changed the patch and the description (in the spirit of Igor's wording).

The result:

 |     test: add clean up for box/access test
 |     
 |     The commit e8009f4158fc2d6efa2824cd634564b3c7a2f899 ('box: user.grant
 |     error should be versatile') did not do proper clean-up: it grants
 |     non-default privileges for user 'guest' and does not revoke them at the
 |     end. That caused occasional failures of other tests, all with the same
 |     error saying user 'guest' already had access on universe.
 |     
 |     This case should be handled by test-run in a future, see [1].
