test_create_space might check acl before actual acl checks in cas

The following discussion from !767 (merged) should be addressed:

• @d.rodionov started a discussion:

  Hmm, I think, the whole test_create_space replaces access check that is invoked for create table op. It doesnt feel good or bad, this just quite obscure. Alternative can be to attempt creation from admin for validation and leave access control check for other machinery.

  It is weird to say, but now it feels like the whole acl thing could've been implemented in this try/rollback fashion
