fix: Distribution module balance should be >= module holdings on startup

Certain modules (e.g. ccvprovider) assign truncated fractions as
rewards, and transfer the full integer amount to the distribution
module. So a long-running chain will almost always fail the assertion if
the module holdings are expected to equal the balance
