should `pak::pkg_install(character())` immediately fail?

[jmbarbone]

otherwise it just keeps searching ...

foo <- function() {
  setTimeLimit(elapsed = 10)
  on.exit(setTimeLimit())
  pak::pkg_install(character())
}

try(foo())
#> Error in rethrow_call(c_processx_poll, pollables, type, as.integer(ms)) : 
#>   reached elapsed time limit
