Fix a small bug in electric quoting.

Before this commit, if 'electric-quote-replace-double' is non-nil,
typing " '" turned into " ‘" even if
'electric-quote-context-sensitive' was nil.

* lisp/electric.el (electric-quote-post-self-insert-function): Insert
context-sensitive double quote only if the last character is actually
a double quote character.

* test/lisp/electric-tests.el
(electric-quote-replace-double-no-context-single): New unit test.
