fix: Unnecessary username validation on account profile form

[yash-rajpal]

Proposed changes (including videos or screenshots)

Issue(s)

Steps to test or reproduce

• Don't allow users to change username, turn off "Allow change of username" setting.
• Open Account profile form
• Try to update any form value
• Can't save form as it always tries to validate username and fails since setting is off
