[DEFECT] Optimizer does not correctly work with Initial Points

[JunyungKim]

Thank you for the defect report

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

Defect Description

There are two issues regarding to initial points submission in RAVEN Optimizer (i.e., ravenframework/Optimizers/Optimizer.py)

1. Even though users provide the initial points in the RAVEN input deck, RAVEN uses randomly generated values for variables, not the ones provided by users.
2. There is no test file, testing whether simulations with initial points written in RAVEN input deck are well performed.

Steps to Reproduce

1. copy one of the test files such as... \raven\tests\framework\Optimizers\GeneticAlgorithms\discrete\constrained\testGAMinwRepConstrained.xml
2. Rename the copied file as "testGAMinwRepConstrainedwInitialPoints.xml."
3. Add block. (Please see the figure below)
   
4. Run the file.

Expected Behavior

RAVEN needs to run simulations with given initial values of variables.

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?
