channeldb: relax bucket assumptions for latest db migration
In this commit, we no longer assume that the bucket hierarchy has been
created properly when applying the latest DB migration. On older nodes
that never obtained a channel graph, or updated _before_ the query sync
stuff was added, then they're missing buckets that the migration expects
them to have.

We fix this by simply creating the buckets as we go, if needed.

channeldb

Build Status MIT licensed GoDoc

The channeldb implements the persistent storage engine for lnd and generically a data storage layer for the required state within the Lightning Network. The backing storage engine is boltdb, an embedded pure-go key-value store based off of LMDB.

The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
