Title: fix ListItem* repr for python 2

Fixes unicode errors when the item text is unicode.

Before:
````python
In [1]: from kivy.uix.listview import ListItemButton, ListItemLabel
In [2]: ustr = u'\u20ac'
In [3]: ListItemButton(text=ustr), ListItemLabel(text=ustr)
Out[3]:
() failed: UnicodeEncodeError: 'ascii' codec can't encode character u'\u20ac' in position 21: ordinal not in range(128)>,
) failed: UnicodeEncodeError: 'ascii' codec can't encode character u'\u20ac' in position 20: ordinal not in range(128)>)

After:
````python
In [1]: from kivy.uix.listview import ListItemButton, ListItemLabel
In [2]: ustr = u'\u20ac'
In [3]: ListItemButton(text=ustr), ListItemLabel(text=ustr)
