feat(action-step-form): making one api call when while loop is created

[akash-nixon]

Description

• initially when while loop is created two post network call was created for while loop.
• one is a wrapper test step and another is the actual while test step

Changes

• Due to new v2 Recorder, it creates only one post network call which contains the actual while test step and the wrapper test step is created in testStepService.
• To make this generalised for both recorder test step and normal test step, now there will only one network call will be created
• In testStepService, the function for recorder needs to be called for all cases.

TODO

• in testStepService, the handleWhileTestStepCreate function is now only called for recorder while test step. it needs to be changed to all test steps.
