Patterns match against snapshot instead of instance #40
Pattern matching in the share function matches against the DBSnapshotIdentifier instead of the DBInstanceIdentifier. This results in orphaned snapshots which are not shared, and therefore not copied to the destination account.
An example:
The pattern .+(-production)$ matches all instances that end in -production. Given an RDS instance django-production and an RDS instance django-production-reporting, we want to copy the first but not the second.
The pattern matches correctly when taking snapshots, but appends YYYY-MM-DD-hh-mm to the DBSnapshotIdentifier. When the share function executes, the DBSnapshotIdentifier does not match the pattern, so the snapshot is not shared.
