csharp: Iterate more in GC-dependent test
The inheritance test depends on the objects being actively destroyed.
Currently this happens in a two step process, where first the C#
object is collected from the GC. As this happens in a separate thread,

This commit adds more iterations to make sure the EO of the parent is
unref'd and releases the child.
This should be the last C#-related CI test failure
