Ensure that IBC has been integrated properly.

Issue identified from local testing with CertiK Chain and Regen Ledger

1. Light client initialization fails despite the success message:

$ rly light init yulei-1 -f
successfully created light client for yulei-1 by trusting endpoint http://localhost:26657...

$ rly chains list
 0: yulei-1              -> key(✔) bal(✔) light(✘) path(✔)
 1: regen-1              -> key(✔) bal(✔) light(✘) path(✔)

2. Relayer fails to link two chains:

$ rly tx link demo -d -o 3s

I[2021-03-22|13:32:41.416] - [yulei-1] -> creating client on yulei-1 for regen-1 header-height{767} trust-period(330h0m0s)

@hacheigriega very nice catch HY. 1 would be hard to catch if you were linking two live chains I suppose.

2 is exactly when I encountered when attempting to link our chain and regen's testnet.

Thanks @jim380 . 2 is now also fixed but now recipient’s balances are not updated after a transfer despite no errors.
