Allow configuring full name if inviting a managed account for the first time

Issue Summary

Incorrect full name set when invited user does not use "Invite link" sent on their mail and logs in directly via social login. 

Steps to Reproduce

1. On inviting a user via email we default to the username provided in the email address. Ex: Sending an invite to user.test@example.com will set the username as the user.test
2. User receives a link to join the site and on clicking the invite link, the user is provided with the option to set user name/ full name.
3. If the user skips step 2 and logs in to the Atlassian site directly via social login "Continue with Google", we don't provide the option to change the user name in this login flow. Here the user name will be the user.test
4. Option now is org admin changes user name under the managed account or user changes this on his profile at id.atlassian.com

Expected Results

Users should be prompted to set Full name on first login or admin should have the option to set Full name while sending invites.

Actual Results

Incorrect full name is set for the user and users believe this full name was by admin for them.

Workaround

Users can change the full name at https://id.atlassian.com/manage-profile/profile-and-visibility

or org admin can change it under managed accounts manually and also via API.
