fix vet error

[corylanou]

Master was currently giving me this vet error:

$ go vet ./...
stats_test.go:86: arg bar for printf verb %s of wrong type: *github.com/influxdb/influxdb.Stats
exit status 1

I'm not sure how this was passing travis/circle on the servers.

Merging on green.

What does # mean?

Assuming # is not an error, +1. Thanks @corylanou

%#v will print type/field information, helpful in debugging.

package main

import "fmt"

func main() {
    foo := struct {
        name string
        id   int
    }{
        name: "Joe",
        id:   1,
    }
    fmt.Printf("%v\n", foo)
    fmt.Printf("%#v\n", foo)
}

Outputs:

{Joe 1}
struct { name string; id int }{name:"Joe", id:1}

My bigger concern wasn't that we had a vet error, but that travis/circle didn't go red.

The test failure is due to #1962, and I can't fix that until this is merged, so merging this even with a failed integration check.
