ionic cordova resources keeps using default image instead of custom images

**Description:**
I have been working on an AngularJS 1.5, Cordova cli v 8, and ionic cli v2 app for a while.
I upgraded my ionic cli to version 3.

I wanted to take advantage of the new **ionic cordova resources** command so I can generate the new splash screens for the iPhoneX etc.

I updated my resources/icon.png file and resources/splash.png to the new specifications: 1024x1024 and
2732×2732px.

I ran the command **ionic cordova resources** and it did generate some new images and updated the config.xml file but it used the default logo instead of my custom one.

I am not sure what I am going wrong.

**My `ionic info`:**
[WARN] Error with .\www\lib\ionic\version.json file: FILE_NOT_FOUND, trying .\bower.json.

Start by running `ionic cordova resources` with the reported `resources/icon.png` and `resources/splash.png` inputs, then inspect the generated images and `config.xml`. Compare the generated assets with the custom source images; done means the command uses the custom images rather than the default logo.
