[text] Queue a redraw when the selection is cleared

Browse Source 
If you select all the text in a ClutterText, there is an invisible
cursor position either at the beginning or end. If it's at the beginning,
the bug is that left arrow won't clear the selection. If it's at the end,
the bug is that the right arrow won't.

Here are the ways to reproduce it:

a. Ctrl-A selects all and moves the hidden cursor position to the left.
b. For single line: End, Shift-Home does the same.
c. Or manually moving to the end and doing Shift-Left Arrow to the
   beginning.

These all put it in the state where right arrow will properly clear
selection and move to cursor position 1, but left arrow fails to clear
the selection.

For b and c above, the opposite will give you the end case where right
arrow doesn't work.

Anyway, it turns out clear_selection is getting called, it just doesn't
show up because it's not doing a queue_redraw. So the attached patch
seems to fix things.
