Link data missing on emulated application nodes

[Xylus]

Call counts on edges pointing to emulated application nodes are calculated from callee statistics rather than caller statistics. This is done because the caller cannot differentiate which emulated application node it has called as the caller only knows the host name of it's target (and emulated application nodes share the same host name).

When such emulated application nodes sit on the edge of the callee search depth (for example, inbound depth=1, outbound depth=2 on a USER -> SELECTED NODE -> EMULATED NODE -> some node), the callee statistics of the EMULATED_NODE is not fetched as the inbound depth limit is 1.

In these situations, the server map incorrectly renders the above as USER --N--> SELECTED NODE --0--> --N--> some node.
