Fix JS bug when enabling MFA during login

Description

When email MFA is not enabled, you may see an exception in the JS console.

Uncaught TypeError: Cannot read properties of null (reading 'querySelector')
    at #handleOnSubmit (OAuth2TwoFactorEnable.js?version=1.45.3:40:34)
#handleOnSubmit @ OAuth2TwoFactorEnable.js?version=1.45.3:40

Observed in version

1.45.3

Affects versions

TBD

Workaround

This error should only be causing noise on the JS console. If you want to fix it, and you are only using OTP and not Email or SMS, add this to the template to work around the JS error.

 <form id="send-two-factor-form" action="${request.contextPath}/oauth2/two-factor-enable" method="POST" ></form>
