> Re-enable TouchCursorInTextfieldTest with some fixes and logs
> 
> Re-enabled TouchEditableImplAuraTest.TouchCursorInTextfieldTest with two
> fixes:
>  - Changed focus_textfield() in touch_seleciton.html to collapse
>    selection after focus, since nothing should be selected after
>    focusing the textfield.
>  - Added a wait between dragging the handle and getting the cursor
>    position in the test to be sure that the cursor position is updated
>    completely.
> Also, added some logs in the test so that if it failed again, more data
> is available for investigation.
