Missing test cases in state recovery init command

[mitsuaki-u]

Expected behavior

1. Missing tests from QA sheet:

• trs.params.chainID is empty
• `terminatedStateAccount(trs.params.chainID) does not exist (and the previous conditions return True)

2. Extra exception logic included in code that was not in LIP specs to investigate:
   In verify hook:

		if (!terminatedStateAccount.mainchainStateRoot) {
				throw new Error('Sidechain account has missing property: mainchain state root');
			}

Recommend updating error message to Sidechain account in terminated state has missing property: mainchain state root

Actual behavior

Missing tests

Steps to reproduce

Cross check QA sheet with code

Which version(s) does this affect? (Environment, OS, etc...)
