Enterprise have access to the internal payment method by default.
The access is handled at the application level so we don't have to
manage database links.
I had to change some specs to keep them simple but I don't think
anything is broken. In one case, it would have needed a lot more setup
to make the spec work. But in production, the permissions are never used
with ModelSet, for example.
The mismatched use of hash attributes as strings and hash attributes as symbols here (attrs['name'] and attrs[:name]) meant that the conditional was not returning the expected results in the test.
