Exception thrown in copy constructor when copying empty optional

[Andoku]

May be I don't understand something, but how this line is supposed to work if method value() always checks assert(has_value())? As i understand it we will always get exception when trying to copy empty optional.

Thanks @Andoku , for spotting & reporting this.

Added the missing test case and corrected the behaviour.

@martinmoene I think assignment operator has the same problem
