When using electric-pair-mode, electric-pair-conservative-inhibit
doesn't respect electric-pair-preserve-balance. For example, type out a
string, go to the beginning of the line, type ", go to the end of the
line, and type ". You are left with "foo"". (Exact keys from the start
of a line are fooC-a"C-e", if that's more clear.) I would expect to be
left with "foo" instead.

This is easy to resolve in your init file (after some digging), but I
think the current behavior is non-intuitive.

Please consider the attached patch.
