case example of bug

When embedding mono into an application and handing over the control
to the managed code with mono_runtime_invoke, the application_base of the
domain setup is not being set. mono_runtime_exec_main on the other site
sets it correctly.

If the application_base is not set correctly,
AppDomain.CurrentDomain.BaseDirectory returns null. 

It is possible to avoid the problem by running mono_runtime_exec_main on an
empty function, but it is clearly a lack of public api or functionality.

In my case I used NHibernate in an embedded mono app and somewhere deep down
in the code AppDomain.CurrentDomain.BaseDirectory was called and its value was
used in Path.Combine. Since it returned null, an exception was thrown.

Look at the attached file, it contains case scenario of the described problem.
