Fix graphing of tool inputs

Graphing of tool inputs to algorithms was broken by !225 (merged) and this was causing the nightlies to fail. After fixing that I noticied some other funky features so fixed those to.

This is the current HLT2 reconstruction data flow after the changes:

One thing to notice in the flow graph: there's an orphan input, VPClus/VPClus_out_ClusterLocation, that's not represented by a proper algorithm node. I think this happens because the VPClus algorithm output is only consumed by a tool, and so the way we traverse up the control flow misses this.

What do you think @nnolte?
