Crash on "merge" branch

[luisnaranjo733]

Description

As an Ethereum user, I want to run Besu on Kintsugi to help so that I can help test the merge.
Specifically, I'm drafting a write-up to help people run Besu-Teku at home against Kintsugi. My goal is to promote the Besu-Teku combo, because I think it's underrated and its success can help improve Ethereum client diversity.

Besu immediately crashes on launch.

Acceptance Criteria

Besu should run normally against the merge testnets

Steps to Reproduce (Bug)

1. Clone and build Besu on the "merge" branch
2. Run it with the flags listed here (copied from the official merge testnet documentation)

Expected behavior: Besu should run

Actual behavior: Besu crashes - something about a missing coinbase transaction and mining (which I'm not trying to do)

Frequency: 100%

Versions (Add all that apply)

All of these details are in this Github gist

• Software version: [besu --version]
• Java version: [java -version]
• OS Name & Version: [cat /etc/*release]
• Kernel Version: [uname -a]
• Virtual Machine software & version: [vmware -v]
• Docker Version: [docker version]
• Cloud VM, type, size: [Amazon Web Services I3-large]

Additional Information

User was including MINER in the --rpc-http-api flags, so besu wanted --miner-coinbase and --miner-enabled as well and was crashing without them.

[SeaMonkey82]

Update: I just tried a fresh instance of besu and it refused to launch without --miner-coinbase, but if I include it while omitting --miner-enabled it just generates a warning and proceeds.

WARN | Besu | --miner-coinbase has been ignored because --miner-enabled was not defined on the command line.

[luisnaranjo733]

Can confirm that adding this flag showed the same warning, and then besu just started chugging along

--miner-coinbase=0x0000000000000000000000000000000000000000

Thanks @SeaMonkey82!
