fix: roles not updating while registration in role selection and data verification steps.

[shubhamv-ss]

Description

Roles are not updated during the registration process in role selection and data verification steps if the user navigates between steps.

Why

• When completing the registration, on third steps if we select any roles and navigate till last step, where we have selected roles section.
• Now if user navigate back to the third step, made some changes.
• Again navigate to last step, here these roles are not getting updated.
• Navigate back to third step, you will see the old data instead of latest roles.
• This issue is addressed in this MR
