Subgraph copy constructor doesn't copy all the data for children subgraphs

Description

Subgraph copy constructor doesn't copy all the data required for normal working in case of the subgraph object actually represents children subgraph. As a result, copied object is not equal to original one and usually can't be used any more.

Here's the data fields that aren't copied:

  1. m_graph (is copied only in case the subgraph object represents root subgraph).
  2. m_local_vertex and m_local_edge containers (ok for root subgraph, data loss for children subgraphs).

The patch with fix is attached.
