Intercept and correct input type `bool` in reqparse dicts

See this issue for a discussion around how RESTplus parses the string “false” as true with type=bool.

We can fix this by intercepting the boolean parameter in the dicts that are being passed in @accepts or @reponds and casting them to flask_restplus.inputs.boolean

First install pytest (pip install pytest), and then run pytest

There’s a pytest.ini file at the root source directory that configures pytest for you

isinstance should be preferred when checking the type of an object because it will also, in general, check subclasses of the type. In this specific case, it so happens that bool cannot be subclassed, but for consistency and readability isinstance is still better.
