fix: process correctly podfiles without platform's version

Steps to reproduce:
1. `tns create myPodApp --js`
2. `tns plugin add nativescript-imagepicker`
3. `tns plugin add nativescript-facebook`
4. Open `node_modules/nativescript-facebook/platforms/ios/Podfile` and replace the file's content with `platform :ios`
5. Open `node_modules/nativescript-imagepicker/platforms/ios/Podfile` and replace the file's content with `platform :ios, '9.0'`
