[issue14591] Value returned by random.random() out of valid range

Here's a modification of Serhiy's patch that assures that the new state is nonzero.

(Just to clarify the nonzero requirement:  the MT state is formed from bit 31 of mt[0] together with all the bits of mt[i], 1 <= i < 624.  At least one of these 19937 bits must be nonzero.)
