throw inline functions need to keep exception type

As it is useful for functions calling BlockchainDB functions to know
whether an exception is expected (attempting to get a block that doesn't
    exist and counting it missing if not, to save time checking if it
    does, for example), the inline functions throw{0,1} need to keep the
exception type information.

Slight comment update due to copy/paste failure.
