• Issue: Odk credential fields are shown even when default odk option is choosen #2140

Describe this PR

Whenever users select an organisation without any default ODK credentials, they are suggested to provide credentials input. But if they wish to use default ODK credentials, they should be allowed to use the default from HOTOSM. So there was an issue when they checked the box to use default ODK credentials; the custom ODK fields input was still shown.

So I removed the logic tied with the organisation in order to show custom ODK fields; this PR only checks if the user has checked the box or not. Based on that, the custom fields to provide credentials are shown.

After merging I can't click next / the ODK credentials fields are mandatory (although hidden):

I think that issue existed before this PR somehow - I will fix it 👍

I fixed the validation problem in the commit above 👍

Personally based on discussion in #2137 (comment), I think this PR should be reverted. But let me know your thoughts there & we will update accordingly.
