Use @flow-weak to avoid errors in Flow 0.14

I'm attaching the errors below in case someone prefers to actually fix them instead. I didn't know what to do about the "Computed property cannot be assigned with possibly null/undefined value" ones, in particular.

RCTRefreshControl.ios.js:30:23,29: parameter configs
Missing annotation

RCTRefreshControl.ios.js:30:32,39: parameter callback

Oops, I guess @flow-weak isn't even the correct syntax (so the effect is simply to disable Flow)...
