Fix failing pubnet conversion test (#226)

The "Public network conversion looks reasonable" test expects the
Stellar expert validators to belong to a coreset called `expert`.
However, #220 changed some of the coreset name mangling logic, so the
expected name is now `expert-non-tier1`. This PR fixes the test to check
for the correct name.
