Fix Oasis account name lookup on pontus-x runtimes

On Pontus-X runtimes, we need to look for named accounts in two sources:
 - The named address repository at Oasis Nexus
 - The named address repository at deltaDAO

This commit re-enables the first source, which was somehow lost
along the way. (The second source was always working properly.
that's why we didnt' notice earlier.)
