key id clashes across algorithms cause problems with statistics

Job #2743211 failed for 785d021d:

Key id 756 is a duplicate. The stats channel only has 756 once in its output when it is expected to be there twice.

The same key id across multiple algorithms.

Kmanykeys.+008+00756.key	Kmanykeys.+008+00756.state	Kmanykeys.+013+00756.private
Kmanykeys.+008+00756.private	Kmanykeys.+013+00756.key	Kmanykeys.+013+00756.state

It looks like the XML correctly captures both counts but JSON doesn't.

I think we are going to have to embed the algorithm into the counter names.
