shim_question behaves the same as utils::? for nonexistent objects

Code
  (expect_error(utils::`?`(foofoo(123))))
Output
  <simpleError in .helpForCall(topicExpr, parent.frame()): no methods for 'foofoo' and no documentation for it as a function>
Code
  (expect_error(shim_question(foofoo(123))))
Output
  <simpleError in .helpForCall(topicExpr, parent.frame()): no methods for 'foofoo' and no documentation for it as a function>

dev_help gives clear error if no packages loaded

Code
  dev_help("foo")
Condition
  Error in `dev_help()`:
  ! Can't find development documentation because no in-development packages loaded.
  i Do you need to run `pkgload::load_all()`?

complex expressions are checked

Code
  (expect_error(shim_help({
    foo
    bar
  }), "must be a name"))
Output
  <error/rlang_error>
  Error in `shim_help()`:
  ! `topic` must be a name.
