Assemble: Fix starting array with initial reshape checkpoint 

If array was stopped during reshape initialization,
there might be a "0" checkpoint recorded in metadata.
If array with such condition (reshape with position 0)
is passed to kernel - it will refuse to start such array.

Treat such array as normal during assemble, Grow_continue() will
reinitialize and start the reshape.
