feat(interactive): Do create the graph when receiving the graph schema for AdminService

[zhanglei1949]

Currently, when creating a new graph, we actually only dump the schema onto the disk and do not actually create a truly empty graph(here empty means no vertices nor edges are added to the graph). Because at the time when we implement AdminService, creating a graph without not data is not allowed.

Now as creating an empty graph is supported by storage, we can create a graph with no data, when receiving a create graph request.

This issue can be resolved by opening an empty graph.
