[DEFECT] Undefined or incorrectly defined constrain functions are not checked until second iteration of optimization.

Thank you for the defect report

• [X] I am using the latest version of RAVEN.
• [X] I have read the Wiki.
• [X] I have created a minimum, reproducible example that demonstrates the defect.

Defect Description

If an optimizer is created with a constrain function (Implicit or explicit). RAVEN does not first check whether or not the constrain function exists or if it is implemented correctly prior to running a routine. After one full iteration of the optimization routine is complete, then RAVEN does properly catch the error. It would be beneficial to catch such errors up-front rather than waiting for one complete optimization set.

Steps to Reproduce

Un defined or incorrectly defined constrain function.

Expected Behavior

An error to be thrown if constrain function is not defined or incorrectly implemented.

For Change Control Board: Issue Review

• [ ] Is it tagged with a type: defect or task?
• [ ] Is it tagged with a priority: critical, normal or minor?
• [ ] If it will impact requirements or requirements tests, is it tagged with requirements?
• [ ] If it is a defect, can it cause wrong results for users? If so an email needs to be sent to the users.
• [ ] Is a rationale provided? (Such as explaining why the improvement is needed or why current code is wrong.)

For Change Control Board: Issue Closure

• [ ] If the issue is a defect, is the defect fixed?
• [ ] If the issue is a defect, is the defect tested for in the regression test system? (If not explain why not.)
• [ ] If the issue can impact users, has an email to the users group been written (the email should specify if the defect impacts stable or master)?
• [ ] If the issue is a defect, does it impact the latest release branch? If yes, is there any issue tagged with release (create if needed)?
• [ ] If the issue is being closed without a pull request, has an explanation of why it is being closed been provided?
