Try to fix rewrite for self file extension method about fastscriptreload

[handzlikchris]

Thanks - I think extensions are also part of other feature. Off top of my head there were some more issues with that unfortunately.

I think especially for rewritten code where YourType would end up YourType__Patched_ and extension method will complain.

We could probably cast it to (ProperType)(dynamic)variable. That's a hack for compiler as your variable is still of old type, same approach is used for something else already (I think for 'this' rewritting)
