Revert "[buildbucket] Speculative fix for handling errors when batch scheduling."

This reverts commit d10db6f2b6c12903b5ebbfc49562803089d0937a.

Reason for revert: caused panics, so the assumption that ret and err have the same length appear to be wrong

Original change's description:
> [buildbucket] Speculative fix for handling errors when batch scheduling.
>
> This changes the error handling code to make sure that every item in
> the returned batch is either a Build or an error, with an error
> taking precedence.
>
> I'm not certain that this will actually fix the issue, but the code
> location in question seemed like it could have allowed a non-nil,
> but empty, build to override an error in the response.

luci-go: LUCI services and tools in Go

GoReference

Installing

LUCI Go code is meant to be worked on from an Chromium infra.git checkout, which enforces packages versions and Go toolchain version. First get fetch via depot_tools.git then run:

fetch infra
cd infra/go
eval `./env.py`
cd src/go.chromium.org/luci

It is now possible to directly install tools with go install:

go install go.chromium.org/luci/auth/client/cmd/...@latest
go install go.chromium.org/luci/buildbucket/cmd/...@latest
