database replicas: set uuid on read.

[andrewsomething]

As pointed out in #878, we've exposed the uuid of a database replica, but it is not set during imports. We only set it in the create method. It should be set in the read method as well.

Test change on its own shows the problem:

=== CONT  TestAccDigitalOceanDatabaseReplica_importBasic
    import_database_replica_test.go:23: ImportStateVerify attributes not equivalent. Difference is shown below. Top is actual, bottom is expected.
        
        (map[string]string) {
        }
        
        
        (map[string]string) (len=1) {
         (string) (len=4) "uuid": (string) (len=36) "bcb92ee3-5f0b-4b90-8a43-a0350b718396"
        }
--- FAIL: TestAccDigitalOceanDatabaseReplica_importBasic (509.30s)

Fixed with the code change:

=== RUN   TestAccDigitalOceanDatabaseReplica_importBasic
=== PAUSE TestAccDigitalOceanDatabaseReplica_importBasic
=== CONT  TestAccDigitalOceanDatabaseReplica_importBasic
--- PASS: TestAccDigitalOceanDatabaseReplica_importBasic (601.54s)
PASS
ok      github.com/digitalocean/terraform-provider-digitalocean/digitalocean/database   601.579s
