[Fix] Setting batch after finalize/initialize

[Fix] Setting batch after finalize/initialize

This patch delays setting batch after finalize/initialize.

Setting batch must be done after runcontext has made, the reason is that
we have semantics that finalize should be independent of batch size, but
if batch size is set before output_dims batch must be set according to
input_dims batch, which is not desirable.
