Now perf test changes/failures will have two rows, row for new and row
for old server.

I thought about uploading only the time of the test on the new server,
but because not all perf tests uploaded, you cannot always get the time
of the test without the changes (i.e. from run on the upstream/master
repo/branch).

<details>
