channeldb: ensure the edge index bucket is created during creation

Browse Source 
Previously, the edge index bucket which maps a channelPoint ->
channelID wasn’t properly created one start up during the initial
creation of the database. This caused some extraneous failure as
queries would unnecessarily fail with bucket non-existence errors.

To fix this we now properly create the bucket on start up if the
database doesn’t exist, and also properly delete the bucket within the
Wipe() function.
