New load message repeats package name

[mfherman]

This mostly is an aesthetic issue, but I notice that when loading tidyverse 1.2.1, the startup message will recycle and reprint the name of a tidyverse package if you load an odd number of packages with the library(tidyverse) call. This would be the case if you previously load one of the tidyverse packages and then call library(tidyverse). Below are examples that demonstrate this.

No repeats:

library(tidyverse)
#> ── Attaching packages ──────────────────────────────────────────────── tidyverse 1.2.1 ──
#> ✔ ggplot2 2.2.1.9000     ✔ purrr   0.2.4     
#> ✔ tibble  1.3.4          ✔ dplyr   0.7.4     
#> ✔ tidyr   0.7.2          ✔ stringr 1.2.0     
#> ✔ readr   1.1.1          ✔ forcats 0.2.0
#> ── Conflicts ─────────────────────────────────────────────────── tidyverse_conflicts() ──
#> ✖ dplyr::filter() masks stats::filter()
#> ✖ dplyr::lag()    masks stats::lag()

Repeats tibble:

library(ggplot2)
library(tidyverse)
#> ── Attaching packages ──────────────────────────────────────────────── tidyverse 1.2.1 ──
#> ✔ tibble  1.3.4     ✔ purrr   0.2.4
#> ✔ tidyr   0.7.2     ✔ dplyr   0.7.4
#> ✔ readr   1.1.1     ✔ stringr 1.2.0
#> ✔ tibble  1.3.4     ✔ forcats 0.2.0
#> ── Conflicts ─────────────────────────────────────────────────── tidyverse_conflicts() ──
#> ✖ dplyr::filter() masks stats::filter()
#> ✖ dplyr::lag()    masks stats::lag()

Doh. Thanks for the bug report!
