Tab title translation doesn't adjust when moving tabs.

When first creating tabs with i18n translation and then drag and drop them into another position, the translations references are not updated.
For example, when i create 2 view tabs with title Tab 1 and Tab 2. Then translate them in the i18n translate interface to Translation 1 and Translation 2.
- Tab 1 --> Translation 1 (quicktabs:tab:frontpage_tabs-0:title)
- Tab 2 --> Translation 2 (quicktabs:tab:frontpage_tabs-1:title).

If i then change the position of the tabs in the edit quicktab settings. The translations references are not updated:
- Tab 2 -> Translation 1 (quicktabs:tab:frontpage_tabs-0:title)
- Tab 1 -> Translation 2 (quicktabs:tab:frontpage_tabs-1:title)
