move this import to existing imports section, before luci-go imports

also no need to alias as "context", it is already "context"

Done.

TBH, i learned to ignore import sections in GO thanks to goimports, but I guess
i had some copy-pasta-caused issues.

gRPC methods should always return grpc errors, e.g. grpc.Errorf(codes.Internal,
"datastore error - %s", err)

Done.
