fix(14): WR-05 import every key of an object-shaped models repeater

A repeater saved with non-sequential keys was read only at keys 0 to
len-1, so a model at a higher key was dropped while the import reported
success and refused to run again. Every key is now read, numeric keys in
ascending order.
