Issue Description

Received this error when attempting a test run:

OneTimeSetUp: BoDi.ObjectContainerException : Multiple public constructors with same maximum parameter count are not supported! System.Globalization.CultureInfo (resolution path: TechTalk.SpecFlow.FeatureContext->TechTalk.SpecFlow.FeatureInfo)
  Exception doesn't have a stacktrace

Steps to Reproduce

Set up with 2 classes for test hooks.

1:

        [BeforeTestRun(Order = 0)]
        private static void BeforeTestRun(IObjectContainer container, FeatureContext fContext, ScenarioContext sContext)
        {
            // stuff here
        }

2:

        [BeforeTestRun(Order = 0)]
        public static void BeforeTestRun(IObjectContainer container, FeatureContext fContext, ScenarioContext sContext)
        {
                    // stuff here
                }

If I remove the parameters from at least one of the two methods, this error does not occur.

This error results from attempting to resolve the FeatureContext and/or the ScenarioContext as parameters of the BeforeTestRun hook. Those objects aren't available at that time in the sequence of execution. BoDi (SpecFlow's object container) attempts to resolve those objects using it's default object construction mechanism but it is not sophisticated enough to do that properly.

Instead, use the other hook attributes, such as BeforeFeature or BeforeScenario, that are appropriate to your situation.

That's very helpful, thanks.
