[Fix #537] Fail early in cljr-rename-symbol if narrowing is in effect

[rechvs]

Previously the function would report a successful renaming without actually having renamed anything (see #537).

I tried to add a test, but make test results in

cask exec buttercup -L .
Warning (emacs):
clj-refactor.el:78: First line is not a complete sentence
...
Failing due to checkdoc warnings...
make: *** [Makefile:35: unit-tests] Error 1

even when executed in the master branch, so I had no way of knowing whether my test would have actually worked. Is this expected? Or am I misinterpreting the output?
(Taking the risk of stating the obvious here:) It would be nice if the CircleCI checks would work again, so I could compare my local setup with the CI one to find out what’s causing the tests to fail on my machine.

Nevertheless thanks a lot for your work on this project. ❤️ After working with IntellIJ IDEA for quite some time now, I’ve really grown fond of its refactoring capabilities, so cljr-rename-symbol in particular is a real godsend.

Thanks much!

I'll check what's going on with CI as soon as I have the chance.

Won't it be better to just ignore the narrowing instead?

Won't it be better to just ignore the narrowing instead?

As I said in #537: that would also be my preferred option. But I’m of course in no position to decide whether that’s the way forward.

This commit is into the 3.7.0 release and will be visible in MELPA/etc within a couple hours.

Thanks!
