Evas Textblock: Fix text disappear issue when text is made up with multiple items.

Summary:
Text is disappearing when we resize a singleline Evas Textblock with ellipsis.
It is happened by putting a Text item at logical_items list without considering about logical position.
It is only happended the text is made up with multiple items.
@fix

Test Plan:
1. Run elementary_test
2. Click Label Ellipsis
3. Resize the window dynamically and see the result.
