Reproduction solution

This bug may be the same as https://bugzilla.xamarin.com/show_bug.cgi?id=44813 but on the current Alpha channel release for Mac (Xamarin.Android

Our internal development landscape certificate has a wildcard as part of the subject, such as '*.mmx.sap.corp'. The current Alpha channel release seems to handle wildcards not correctly and reports a 'RemoteCertificateNameMismatch' SslPolicyError to the callback registered to to `ServicePointManager.ServerCertificateValidationCallback`.

This works in Stable. Hence we believe we are facing a regression here.

Repro attached. Assign URL of test server to constant in MainActivity.cs line 18.
