yield without try-except

[hhamana]

Fix for #74 : yielding within a try-except block executes the exit code before a FastAPI error handler is executed, making the context unusable in such situations.
It looks like it didn't need to be in this block, as it is already within a context manager by itself.
Putting this up as I said I'd double check the fix, and haven't actually checked as thoroughly as I wanted but the idea is simple, it shouldn't have taken that long to fix.

I'm not exactly sure this is correct but I was trying to run into regressions and I wasn't able to see any issues.

As I said above, it shouldn't result in any regressions and if true, this is a huge win as many people complained about that.
