client.shell don't run callback

[CheeseYu]

 client.shell(_id, `LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/minicap -P ${phy_x}x${phy_y}@${phy_x*0.4}x${phy_y*0.4}/0`)
    .then(adb.util.readAll)
    .then(function(output) {
        console.log('%s: %s', _id, output.toString().trim())
        return client.forward(_id, 'tcp:9222', 'localabstract:minicap')
            .then(function(output) {
                console.log('Setup devtools on "%s"', _id)
                console.log(output.toString().trim())
            })
    });
