Expand graph in path.subgraph_all when filterStartNode == false

[thomas-tran-de]

Description

When filterStartNode == false, path.subgraph_all would always return the start node. However, it would not expand beyond it if it didn't meet the criteria in labelFilter. This is confusing as filterStartNode == false suggests that it will always be ignored. With this PR, it'll always expand beyond the start node.

In addition, using negative values for maxHops will now be ignored and use the default std::numeric_limits<int64_t>::max() instead.

This is related to #610 . To fix the issue, the documentation should be updated to highlight differences between DFS for path.expand/path.create and BFS for path.subgraph_all/path.subgraph_nodes.
