Remove NotSupportedException assertion in Accept test

The test for the `Accept` method no longer asserts that a
`NotSupportedException` is thrown. The `Assert.Throws` call
was replaced with a direct invocation of the `Accept` method,
indicating that the method is no longer expected to throw
this exception in the given context.
