Fix non-range String init calls

When the String constructor was called via invoke-direct, it is changed
to the new StringFactory which is static. That means that the args need
to be shifted by one to deal with the change from non-static to static.
However, the non-range version of the invoke-direct was not shifted
correctly causing unstarted runtime initialization to get the wrong
first_dest_reg argument.
