Michał Niewrzał c258f4bbac private/testplanet: move Metabase outside Metainfo for satellite
At some point we moved metabase package outside Metainfo
but we didn't do that for satellite structure. This change
refactors only tests.
When uplink will be adjusted we can remove old entries in
Metainfo struct.
