Fix CustomDataView.tpl plain empty memo field.

[mlutfy]

Overview

To reproduce:

• Create a new Custom Field Group: for Contacts, repeatable, in tab form.
• Create 3 fields: a normal text field, a 'note' with TextArea (not wysiwyg), and another text field.
• Then go to a Contact record, and fill in a new instance of that group, but leave the fields empty.
• Then go back to the Contact record, and click 'view' on that entity.

Result: two fields appear to be on the same line.

Before

Two labels on the same line.

After

Each (empty) field on its own line:

Technical Details

Not very elegant fix, but it's what the rest of the template does.
