Failed to show splash image when running cordova on 3.5-inch devices or simulators

If I run Cordova app on 3.5-inch devices or simulators, the splash image is not displayed.
We can run mobile-spec->Splashscreen test to reproduce this phenomenon.

I believe this bug is imported by commit https://github.com/apache/cordova-plugin-splashscreen/commit/75327c88e4463ef3e3507424e4bb411c4365b9ca

The reason is that it can't find image which is named "Default-Portrait".
