Fix incorrect thread with main_thread property

[SilicDev]

Fixes the issue that main_thread would return an incorrect thread object
Inherently the issue is that the generator enum_process_thread acts in place so when sorted tries to create the array to sort, the generator returns the same reference pointer, with changed values after every call, resulting in n copies of the last entry in the thread32 list. This is not even guaranteed to be a thread to be owned by the source process, hence why the query_teb of the ThreadEntry32 fails as the targeted memory is not owned by the source process. Can confirm with this fix I can obtain the SMALL_TEB as seen https://github.com/SilicDev/Archipelago/blob/yohane-deepblue/worlds/yohane_deepblue/client.py#L253

This fix might not be ideal, but it fixes the issue blocking the teb feature.

This indeed seems to fix the issue
I suppose the issue ended up being the byref instead of the generator itself then
