rABCdb21d2ab5109: tests: Represent proof IDs as hex strings when sync_proofs fails

Summary

Internally, the test framework computes and stores proof IDs as
integers. This is not a convenient format when debugging, as the
debug.log message all show proof IDs as hex strings.

Format the proof IDs as hex strings for the AssertionError message.

Test Plan

Run abc_p2p_proof_inventory with the following patch, to cause the error message to be displayed:
