lncli wallet bumpfee with wrong output index

[BjXXQWNQ]

Background

When using lncli to bump the fee of an onchain transaction, the use of a wrong output index crashes lnd.

Your environment

• lnd 0.10.0-beta
• Linux raspberrypi 4.19.97-v7l+ lnwallet/channel: set add heights based on the locked in commits #1294 SMP armv7l GNU/Linux
• bitcoind 0.19.0

Steps to reproduce

1. Open a channel to produce a new onchain funding transaction. The result was in my case a transaction with two outputs.
2. lncli wallet bumpfee [transactionhash]:2

Expected behaviour

Some error message.

Actual behaviour

lnd deamon crashes.
