Status window gives Ecopath run successful message when model is not balanced

[robynf]

Generic 22 model.

Opened model
Summed diet composition to 1
Clicked Basic estimates
Got message that Ecopath run not successful, model not balanced. Correct problem groups highlighted.
BUT this message was immediately followed by a message that Ecopath run was successful
This would be confusing to a new user who might not look at the previous unsuccessful message
