[WCF] Disable CloseTest and OpenTest4 in CustomPeerResolverServiceTest.
These tests occasionally time out:
Test Case Failures:
1) MonoTests.System.ServiceModel.PeerResolvers.CustomPeerResolverServiceTest.CloseTest : System.TimeoutException : The operation has timed-out.
at System.ServiceModel.Channels.HttpRequestChannel+HttpChannelRequestAsyncResult.WaitEnd () [0x00000] in <filename unknown>:0

I.e. we're timing out waiting for the async wait handle here: https://github.com/mono/mono/blob/master/mcs/class/System.ServiceModel/System.ServiceModel.Channels/HttpRequestChannel.cs#L495
Since we have no current WCF maintainer and this is deep, deep within
WCF land and causes unstable builds on Jenkins, disable these tests
for now.
