Webform text format appears in the formats list

Please review the slightly ugly but straightforward solution with the disabled test fixed.

I just realized we can't remove the 'Use the Webform (Default) - DO NOT EDIT text format' permission from the page but we need to hide it using #access: FALSE because we don't want authenticated users to lose the permission.

Looks like we need to use hook_form_alter to hide the permission but we can't use hook_form_alter to remove the filter from the admin because drag and drop show an empty row.

@jrockowitz thanks for working on this! I gave it a manual test and it appears to resolve all instances of this appearing in the UI.

Since there is test coverage and this is a major issue, I am going to merge it and we can fix any additional issue as they come up.

Should we close 💬 The hidden webform text format leads to text format selects with only one option Active now?
