printing caught errors without cli installed does not work

[TimTaylor]

Printing caught conditions doesn't seem work if cli is not installed

library(rlang)
cnd <- tryCatch(abort("bob"), error = identity)
str(cnd)
# List of 5
# $ message: chr "bob"
# $ trace  :Classes 'rlang_trace', 'rlib_trace', 'tbl' and 'data.frame':	5 obs. of  6 variables:
#  ..$ call       :List of 5
#  .. ..$ : language tryCatch(abort("bob"), error = identity)
#  .. ..$ : language tryCatchList(expr, classes, parentenv, handlers)
#  .. ..$ : language tryCatchOne(expr, names, parentenv, handlers[[1L]])
#  .. ..$ : language doTryCatch(return(expr), name, parentenv, handler)
#  .. ..$ : language abort("bob")
#  ..$ parent     : int [1:5] 0 1 2 3 0
#  ..$ visible    : logi [1:5] TRUE TRUE TRUE TRUE TRUE
#  ..$ namespace  : chr [1:5] "base" "base" "base" "base" ...
#  ..$ scope      : chr [1:5] "::" "local" "local" "local" ...
#  ..$ error_frame: logi [1:5] FALSE FALSE FALSE FALSE FALSE
#  ..- attr(*, "version")= int 2
# $ parent : NULL
# $ rlang  :List of 1
#  ..$ inherit: logi TRUE
# $ call   : NULL
# - attr(*, "class")= chr [1:3] "rlang_error" "error" "condition"
cnd
# Error in loadNamespace(x) : there is no package called 'cli'

nor does try_fetch

cnd <- try_fetch(abort("bob"), error = identity)
cnd
# Error in loadNamespace(x) : there is no package called 'cli'
