eliminate some false positives on reportUninitializedInstanceVariable

[beauxq]

This is a common and good pattern that reportUninitializedInstanceVariable currently fails with.

Often we want a class to have a "reset" method to reset it back to its initial state.
But if we initialize everything in __init__, that means we're duplicating code, putting it in both __init__ and in the reset method.
So it's better to just put the initializing code in the reset method and __init__ can call the reset method.

class C:
    x: int

    def __init__(self) -> None:
        self.reset()

    def reset(self) -> None:
        self.x = 3

But the current implementation of reportUninitializedInstanceVariable doesn't see x as initialized.

This is a fix for this problem.
