Oath class cast exception in AuthConfig

Version 3.0.3 affected, version 2.9.0 is not affected.

In line 231 this.service = (OAuth10aService) getOauthService(isOAuth1, addEmptyTokenToBaseString); but getOauthService returns OAuthService with incompatible to OAuth10aService implementation: OAuth20Service. This leads to:

java.lang.ClassCastException: com.github.scribejava.core.oauth.OAuth20Service cannot be cast to com.github.scribejava.core.oauth.OAuth10aService

	at io.restassured.internal.http.AuthConfig$OAuthSigner.process(AuthConfig.java:231)
	at org.apache.http.protocol.ImmutableHttpProcessor.process(ImmutableHttpProcessor.java:133)

Sample execution:

given()
        .accept("application/zip")
.when()
        .auth().oauth2(token, QUERY_STRING)
        .get(Urls.pathToTest)
.then().log().all()

One note: without QUERY_STRING parameter it is working fine (and does not require com.github.scribejava optional dependency).

Also experiencing this problem with a slightly different use - simply trying to set default OAuth2 authentication for all requests:

RestAssured.authentication = RestAssured.oauth2(authToken);

I receive the same exception as reported by @kmaterka above.

To work around this I just explicitly create the OAuth2 scheme:

PreemptiveOAuth2HeaderScheme myScheme = new PreemptiveOAuth2HeaderScheme();
myScheme.setAccessToken(authToken);
RestAssured.authentication = myScheme;

Simply calling oauth2(token) should work based on what I see in the docs.
