Unable to create user with identifier prefix

[mahalakshme]

Steps to reproduce:

• Go to JSCS or any org, env: prerelease
• Go to Admin -> Users -> create a user by mentioning 'Identifier Prefix' -> Click Save
• You will see 'Server communication error'
• Unable to set identifier prefix only in create flow, working in update flow.

Expected:

Should be able to create user with a new identifier prefix unless there exists a different user with the same prefix during which an error will be shown like "There is another user {username} with same prefix: {idPrefix}"
