md_enter_child_containers: Fix crash (issue #10).

Calling md_push_container_bytes() may result in ending a current block
which may result in removing some contents from ctx->block_bytes when
removing some lines with link reference definitions.

This in effect means we have to end the block explicitly before storing
the offset into the ctx->block_bytes.
