If we are testing for an index whose membership bitmask happens to sit in LSB of uword, and there is nothing else set in that uword in the member bitmask, the shortcut path returning the valid index is taken even if the element with a given index doesn't exist in the sparse vector. This happens because the count of leading zeroes on the value of 0 is zero, which is equal to the value taken modulo bitsize uword. Take care of that case. Also add unittests showing the problem and verifying that sparse_vec_index2 does not have the same issue.
