`eval_select()` forces variables in `include` to the front

[mgirlich]

Variables specified with include are forced to the front even when they appear later in the selection. This lead to an issue in tidyverse/dbplyr#568

library(tidyselect)

eval_select(
  rlang::expr(c(a, b)), data.frame(a = 1, b = 1),
  include = "b"
)
#> b a 
#> 2 1
