Revert "Update tests with new clojure-mode indentation"

`clojure-mode` has changed its mind due to unexpected controversy

This reverts commit 3e707e262c9c2cb1e19beb2ddbde477cb6682d61.
Add cljr-add-missing-libspec

`cljr-add-missing-libspec` will try to resolve the symbol at point and
require or import the missing var.  If there are more than one var match
the user is prompted. If there's only one result it is added without
user intervention.  If the symbol at point is of the form
`edn/read-string` the resulting libspec will be aliased to `edn`.

This depends on the middleware to do its thing.
