"probe" directory has different order from other function objects

Hi, @Mattijs.

I'm Jake from South Korea, and I'm working on a GUI for OpenFOAM.
I have a question regarding the path of probe Function Object.
I found that the path for probe is <FOName>/<regionName>/... that is defined in following line

probes.C

    fileName probeDir
    (
        mesh_.time().globalPath()
      / functionObject::outputPrefix
      / name()/mesh_.regionName()
        // Use startTime as the instance for output files
      / mesh_.time().timeName(mesh_.time().startTime().value())
    );

I tried finding the reason why it had different path from other FOs, and came to this commit.

    if (obr_.name() != polyMesh::defaultRegion)
    {
        probeSubDir = probeSubDir/obr_.name();
    }

I still could not find a reason why obr_.name() is after probeSubDir.

What do you think about following change for current code? From

/ name()/mesh_.regionName()

/ mesh_.regionName()/name()

By the way, thank you for your effort in OpenFOAM.
