Subject: [PATCH 2/4] ct_util: Stop using get_stacktrace/0 inappropriately

The return value of erlang:get_stacktrace/0 is not defined
when called like this:

try Expr of
    Pattern ->
      erlang:get_stacktrace()
  end

Currently, the stacktrace will be from a random earlier error.
In a future release, it may be [].

Note: We can remove the entire 'case' statement because
CTHReason can never be an atom.
