...signed/unsigned mismatch

In history this was sal_Long and then converted to sal_uLong, but the
test never got aligned.

Fix it by adding arbitrary element counts starting from 30.

old: getCount():
{-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9}

(With -5 silently converted to SAL_MAX_UINT32 - 5)

new: getCount():
{30,31,32,33,34,0,1,2,3,4,5,6,7,8,9}
