Fix number of chains print method

[gowerc]

Closes #356

Minor side effect was that the main test object I have (which is shared across many tests) only used 1 chain so I had to increase that to 2 for the snapshots to show this change is working; but by doing so it impacted some other snapshot tests which I had to update accordingly.
