[grod220]

Write tests for undelegate action:

web/packages/wasm/crate/src/planner.rs

Lines 358 to 370 in 8bf66ea

	for tpr::Undelegate { value, rate_data } in request.undelegations {
	let epoch = storage.get_latest_known_epoch().await?.unwrap();
	let value: Value = value
	.ok_or_else(|| anyhow!("missing value in undelegation"))?
	.try_into()?;
	let rate_data: RateData = rate_data
	.ok_or_else(|| anyhow!("missing rate data in undelegation"))?
	.try_into()?;
	let undelegate = rate_data.build_undelegate(epoch.into(), value.amount);
	save_unbonding_token_metadata_if_needed(&undelegate, &storage).await?;
	actions_list.push(undelegate);
	}

and undelegate claim action:
