resolve-missing can specify the wrong `:type`

[vemv]

Using (cljr--call-middleware-to-resolve-missing "Thread") returns the following for me:

(#s(hash-table size 2 test equal rehash-size 1.5 rehash-threshold 0.8125 data
               (:name sun\.jvm\.hotspot\.runtime\.Thread :type :ns))
   #s(hash-table size 2 test equal rehash-size 1.5 rehash-threshold 0.8125 data
                 (:name java\.lang\.Thread :type :class)))

...that :type :ns should be :type :class instead, otherwise clj-refactor will try to :require the class.

I'd say that this example shows two issues at once:

• wrong tagging
  • maybe we're using :type :ns too laxly as a fallback
  • ...and it's easy to check if a string is a ns without evaluating it, by checking the underlying resource
• suggestion of odd classes
  • sun.jvm.hotspot.runtime.Thread cannot be imported
