This commit fixes a bug which would previously lead to corruption of the channel state when a node had one or more channels open and one of them was closed either forcibly or cooperatively. The source of the bug itself as a typo: rather than using the construed `deliveryKey` variable to fetch/put/delete the delivery scripts, `deliveryScriptsKey` (the key prefix itself) as used. This bug would cause the database to be unable to read _any_ channel from the database after one was deleted, as each channel would actually be reading/writing-to the _exact same_ delivery script. The fix for the bug itself is simple: eliminate the typo.

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
