Evas textblock: Fixed the bug with disappearing text with many tabs and text.

Evas textblock: Fixed the bug with disappearing text with many tabs and text.
I removed a function that caused the issue and made no sense at all, honestly, it didn't make any sense.
I did a lot of testing trying to see if there are any new bugs after the fix, and nothing, so I guess my instincts were correct.
Please if you can, check out the removed function (_layout_walk_back_to_item_word_redo) and see if it makes any sense to you, if it does, please let me know.
