as_long_data_frame() works correctly with and without names

Code
  ring <- make_ring(3)
  as_long_data_frame(ring)
Output
    from to
  1    1  2
  2    2  3
  3    1  3
Code
  V(ring)$name <- letters[1:3]
  as_long_data_frame(ring)
Output
    from to from_name to_name
  1    1  2         a       b
  2    2  3         b       c
  3    1  3         a       c
Code
  V(ring)$score <- LETTERS[1:3]
  as_long_data_frame(ring)
Output
    from to from_name from_score to_name to_score
  1    1  2         a          A       b        B

  3    1  3         a          A       c        C
Code
  E(ring)$info <- 3:1
  as_long_data_frame(ring)
Output
    from to info from_name from_score to_name to_score
