CocoaPods /platforms/ios/Podfile generation

This generated Podfile (tns command builds it) is built it can get lots of duplicates. Each time you do something that internally does a tns prepare ios or if you manually do a tns prepare ios you will get a duplicate begin, pod and end lines into this file.
Maybe this file should be truncated before adding them back. As when I was fixing my pod file; I ended up getting several of the same pods in the file, but all with different :path variables which then caused it to choke...

Woo Hoo! I'm glad this is almost done; I've ran into another issue as I had to add a post install step to my podfile and because it keeps getting inserted into the file; I start getting warnings about needing to manually fix the podfile due to multiple post install steps.

@NathanaelA Have you tried our latest build from release branch. We'll be glad for any assist that could confirm it works as expected now?

[NathanaelA]

Nope, but I will attempt to try this out...

Steps to reproduce:

1. $ tns create myApp
2. $ cd myApp
3. $ tns plugin add nativescript-iqkeyboardmanager
4. $ tns prepare ios
5. $ cat platforms/ios/myApp/Podfile -> there is something like this:

Begin Podfile

pod 'IQKeyboardManager', '~> 4.0.0'

End podfile

1. $ tns prepare ios
2. $ cat platforms/ios/myApp/Podfile -> lines above are repeated 2 times
