Unexpected return for QueryDistributionRewards

[shifty11]

lens/client/query.go

Line 927 in 2c97550

func (cc *ChainClient) QueryDistributionRewards(ctx context.Context, delegatorAddress sdk.AccAddress, validatorAddress sdk.ValAddress) (sdk.DecCoins, error) {

If I query for rewards and there are none I get a "null". This is unexpected. It would be better to print

[{"denom":"uhuahua","amount":"0"}]

How to reproduce:
