bug#23387: 25.0.93; Unicode quote inserted in Python mode outside of strings

[Philipp Stephani]

emacs -Q
M-x electric-quote-mode
M-x customize-variable RET electric-quote-string, set it to t, save
M-x python-mode
Hit '

Expected: ' (ASCII apostrophe) is inserted because point is outside a string
Actual: ’ (Unicode quote) is inserted

This seems to happen only in Python mode, not in e.g. emacs-lisp-mode.
