`cljr-move-form` throw `IllegalAccessError`

Whenever I use `cljr-move-form` I get a `java.lang.IllegalAccessError` saying that the moved form cannot be found. The problem seems to be that the def of the moved function is not evaluated in the new namespace, which causes the :refer in the current namespace to fail.

## Expected behavior

`cljr-move-form` works without an error.

## Actual behavior

`cljr-move-form` throws `java.lang.IllegalAccessError`.

## Steps to reproduce the problem

Move a function from one namespace to another.
