Fixed:  clientside state restore on redraw (tab switch)

Hi,

It's quick fix for following issue with component state sync:
0. having TabSheet with two tabs
1. place AutocompleteField on Tab 1
2. start app
3. go to Tab 1  and enter some text into AutocompleteField
2. go to Tab 2
3. go back to Tab 1

ER: same text is displayed
AR: empty textbox

Would very cool to see it in next version.
