Better message than explicit panic when initial monetary mass differ from sum of balances in genesis
Motivation
When starting duniter with custom data genesis, if the parameter initial_monetary_mass is not the sum of the balances of all identities + wallets, it exit with code 101 and only a explicit panic message.
Suggested Solution
Maybe we can display a better message for this. It's hard do discover why it fail when testing with custom data...
