Docstrings ending in a double quote break generated code

[JacekLach]

conjure-python will happily generate

def foo(self):
    # type: () -> Optional[str]
    """Foo: returns the string "bar""""
    ...

when given the doc string of Foo: returns the string "bar"

@JacekLach what would be preferred here? does multiline work?

def foo(self):
    # type: () -> Optional[str]
    """
    Foo: returns the string "bar"
    """
    ...

[JacekLach]

yeah I think just injecting a newline before/after the docstring should fix it

#138 did this, and #225 does some more
