fix(tests): accept error 400 for already registered accounts

The IMX API now returns error 400 (instead of 409) when an account
is already registered. Updated the test to accept both error codes
as valid responses for already-registered accounts.

This allows test_4_imx_functions to pass when the account is already
registered.
