Respect nested conditions

I was surprised this didn't work, but seeing that it was just a hash, I kind of get why not. Seemed simple enough to add this behavior as the nested exposures carry this info around.

```
$ rake
Running RuboCop...
Inspecting 9 files
.........

9 files inspected, no offenses detected
.....................................................................................................
