Fix brush with annotations

[betodealmeida]

The brush (time filter) currently does not work with annotations:

I added a new callback that is dispatched when the brush is updated, and now it works:

Hi, I am on v0.25.5 and it seems this fix is intermittently showing up. For instance, when I initially create/save a slice with 1 or more annotations, it works fine with the range brush. However, if I save or retest on a dashboard that contains the slice it shows 2 overlapping layers of annotations. One that moves with the brush and one that is static.

Any idea why this may be. Is this part of a different release? Here is a picture.
