[Bug fix] Forgetting delegation tokens

[grod220]

Two bugs:

1. Spent commitments are being forgotten if they are delegation tokens. Should flip the logic on that conditional.
2. Spent swap commitments are never delegation tokens.

Found while pairing 🍐 with @plaidfinch

The fact that this wasn't detected by the test suite indicates that the smoke test doesn't exercise a relevant path:

• delegate
• proposal submit
• undelegate
• delegator vote

This would have failed before this fix, and should succeed now. I recommend adding this scenario to the smoke tests, perhaps in a follow-up PR?

@hdevalence fyi, we were pairing yesterday and found some oddities while trying to write a smoke test for this:

• In main (before this change), after undelegating, voting appeared to work (not sure how if bug was forgetting)
• Tallys did not show the vote count
• Spent denom not showing unbonding token when we used tracing

@plaidfinch will sync with Aubrey to see get additional eyes on the spent_denom sql query.
