The ascent_initial_time_slack_constraint is not correctly hooked up.

[Kenneth-T-Moore]

Description

The ascent_initial_time_slack_constraint resid constraint has two problems.

1. The constraint has no upper/lower/equals specified.
   This was actually allowed in OpenMDAO, but it results in a con that is always satisfied, which is pointless. OpenMDAO has just fixed this loophole, so this con will raise an error: OpenMDAO now issues a warning if a constraint is added without a lower, upper, or equals. OpenMDAO#3740

2. The constraint is not hooked up to the actual ascent initial time.
