Copied social to a test as a starting point.

Added a basic end to end test using social as the starting point.

You can test it with other engines by supplying GOCRUD_STORE_TYPE environment variable. For example:

GOCRUD_STORE_TYPE=mongodb go test ./... -v

Step in the right direction. I'm thinking of waiting on merging this branch, until you add some tests based upon this change.
