Batch balance primary key already exists when creating a credit batch

[ryanchristo]

Summary of Bug

Receiving the following error when attempting to create a credit batch using the create-batch command:

raw_log: 'failed to execute message; message index: 0: "regen.ecocredit.v1.BatchBalance":[[214
  219 19 241 212 17 89 86 241 77 88 42 4 118 217 62 92 68 199 92] 2]: object with
  primary key already exists'

Also noticed the CLI example includes project_jurisdiction which is no longer used given we provide project_id.
