Should namadac bonds show 0 amount remaining bonds?

[brentstone]

Currently for a client query of the bonds, if there is no amount remaining in a bond, the CLI still prints it. For example, consider a delegation of 200 NAM in epoch 0, then a delegation of 300 NAM in epoch 8, followed by an unbond of 412 tokens, upon querying the bonds, one would see something like:

Delegations from atest1v4ehgw36g4rrxd6pgfp5vwf3x3zrqv6xxue5g3j9xym52d6rx4znyv29xqcrs33eg5unvvzyr35txx to atest1v4ehgw36xgmnys6yxscnsd3cxvcrvvzxxscyvwzygymnj3fkxdz52vp4x3zrw3p3xgmnwse5p73tj8:
  Remaining active bond from epoch 0: Δ 88
  Remaining active bond from epoch 8: Δ 0
Bonds total: 88
Withdrawable total: 0

This may pose an annoyance/issue with the load tester (@bengtlofgren @Fraccaman ?) calculating bonds. Perhaps we want to make sure that this 0-amount bond info does not get written to the output. We could do this by making sure the library code skips over empty bonds, or we could ensure that these bond entries get deleted in storage when their amount gets reduced to 0 during unbond. One possibly valuable bit of information that the current query communicates is that there was a bond submitted during epoch 6 (active at 8), but not sure if we care to convey this.

I think we should filter out any 0s
