Revert of [Android] Don't push deps when listing gtests.

Revert of [Android] Don't push deps when listing gtests. (patchset #1 id:1 of https://codereview.chromium.org/560133002/)

Reason for revert:
While we do want to only attempt to push once, this isn't the right way to do it. We should push _before_ attempting to list the tests, then be done with it.

Also, this breaks https://codereview.chromium.org/537063002/

Original issue's description:
> [Android] Don't push deps when listing gtests.
>
> PushDataDeps takes a long time even when all files are on the device
> because calculating the digests of all the files takes _much_ longer
> on a device than it does on a host.
>
> Skipping the push step during test listing -- where the data deps are
> unnecessary -- means that we don't try to push files twice in each
> gtest run, so we skip all of the device-side MD5 calculations that
> would happen in the second run.
