This lets us expose the component stack to the error reporting that
happens here as `console.error` patching. Now if you just call
`console.error` in the error handlers it'll get the component stack
added to the end by React DevTools.
However, unfortunately this happens a little too late so the Fiber will
be disconnected with its `.return` pointer set to null already. So it'll
be too late to extract a parent component stack from but you can at
least get the stack from source to error boundary. To work around this I
manually add the parent component stack in our default handlers when
owner stacks are off. We could potentially fix this but you can also
just include it yourself if you're calling `console.error` and it's not
a problem for owner stacks.
This is not a problem for owner stacks because we'll still have those
and so for those just calling `console.error` just works. However, the
main feature is that by letting React add them, we can switch to using
native error stacks when available.
The old version of prettier we were using didn't support the Flow syntax
to access properties in a type using `SomeType['prop']`. This updates
`prettier` and `rollup-plugin-prettier` to the latest versions.
I added the prettier config `arrowParens: "avoid"` to reduce the diff
size as the default has changed in Prettier 2.0. The largest amount of
changes comes from function expressions now having a space. This doesn't
have an option to preserve the old behavior, so we have to update this.
