GetAssembly().EntryPoint returns TypeBuilder instead of created type (for assemblies in memory)

```
In Mono TypeBuilder methods can't be invoked (may be for old versions, I'm 
using Unity3d).

Workaround is conversation any type (which you can get from generated assembly) 
to TypeBuilder and calling CreateType. 

Than you can use it.
