Alert content type - Page visibility validation issue

Issue fixed in https://github.com/civictheme/uikit/pull/346

The fix updates the parsing of the incorrect "plain text" from the API but the root cause of this issue is in the `plain_text` field formatter which adds the twig filter `nlbr` to its processing.

The ideal fix will be to change the page visibility field to a multi-value plain text field so it provides an array of page visibility values and we can iterate over the values.

Due to this requiring a new field / update existing field and an upgrade path this will need to be considered.

For the meantime Josh's fix mitigates the issue

Sorry on further inspection I see that we are using a REST display of alert content types see: /admin/structure/views/view/civictheme_alerts

The `visibility` field needs to be updated to strip tags to remove the `
` tags.

Same underlying cause but we have ability to change field output.

I have left a few questions, Josh

Verified and tested on 1.8-dev

Testing Results:
When we set Page visibility condition on Alert content type then validation does not fail for any urls listed - PASS
