Post-signup message don't show after account creation

[jmartinezfl]

Describe the bug

The custom post-signup message does not appear when creating a new account. Instead, the message defined in “Success message” is shown, even though the “Auto redirect on success” option is disabled.

To Reproduce

• Configure a custom post-signup message
• Disable the Auto redirect on success option
• Create a new account
• Verify that the message displayed is the one defined in the Success message section instead of the post-signup message

Same happening on stable/:latest. Checking the config file it shows auto_redirect=false, but the button is not visible.
