Gave the OAuth filter authentication priority.

If you want to use the `javax.annotation.security` annotations and the `RolesAllowedDynamicFeature` with the `OAuth1ServerFeature`, the `OAuth1ServerFilter` needs to have `AUTHENTICATION` priority so that it is executed before the `RolesAllowedRequestFilter` (which has `AUTHORIZATION` priority).  This commit fixes this issue and allows the two to be used together.
