Caret position not taken into account when word prediction is enabled

[Adnane Belmadiaf]

Steps :

1- Enable word prediction
2- Open the webbrowser-app
3- Type "ubuntu" in the search field(not the addressbar, also note that the word is underlined)
4- Move the caret to the beginning of the word, then type "k"

What should happen :
- The finale word should be "kubuntu"

Result :
- You get "ubuntuk"

[Olivier Tilloy (osomon)]

I can reproduce the issue with a simple oxide webview:

import QtQuick 2.4
import com.canonical.Oxide 1.15
WebView {
  url: "http://start.ubuntu.com"
}
