check_tibble(method = "augment") column name tests

[alexpghayes]

Checking augment output against the column names of the input data will result in test failures in cases like the following:

fit <- lm(mpg ~ log(hp), mtcars)
broom::augment(fit)

#>    .rownames   mpg log.hp. .fitted .se.fit .resid   .hat .sigma .cooksd

Not precisely sure how we get to the final augmented column names, but it seems like make.names() gets called at some point.
