Enhance the suggest changes feature to consider the current email of the user in case nothing is provided

Problem Definition

The suggest changes feature present inside the user administration part of Cloud instances only sends the suggested changes to the user in case both his full name and email are provided.

In case the user only provides/suggests a full name change leaving the email field blank a "Something went wrong" message is displayed. When looking at the browser triggered call we can see why the suggest failed:

{"key":"fieldConstraintsViolated","context":{"fieldViolations":[{"field":"suggestChangeDetails.arg1.email.value","violations":[{"key":"Value is not a valid email address"}]}]}}

Basically, if you leave the email field blank the suggest fails.

Suggested Solution

Enhance the feature so when the email field is not filled the application uses the current email of the user, the same goes for the name.

Workaround

Manually fill in the current email of the user before triggering the change.
