Remove ANIMATED_GIF_SUPPORT preprocessor conditionals from unit tests

When we added Carthage support ( #164 ), we created two NYTPhotoViewer targets: the “normal” one which includes animated gif support (via `ANIMATED_GIF_SUPPORT=1`, and requires linking with FLAnimatedImage); and the “-Core” target which does not include animated GIF support.

For brevity I will refer to the library version with animated gif support as “-Normal” even though it doesn’t have that suffix (the “-Core” target _does_ have that suffix).

The unit tests are configured to run against the “-Normal” target, but they weren’t compiled with `ANIMATED_GIF_SUPPORT=1`, so we were running unit tests intended for “-Core” against the “-Normal” target. This resulted in some test failures.

I’ve fixed them by removing the `ANIMATED_GIF_SUPPORT` conditionals from the test target, leaving in the code that should be run against “-Normal”.

I am unsure whether it’s worth making a new “-Core” test target just to include the three assertions (removed in this commit) which were intended to apply to “-Core”. Feedback is welcome.
