Fix null-access errors in "addTo/removeFrom*PbxGroup" methods
The project exposes a few methods to add/remove children from PbxGroups
* `addToPluginsPbxGroup` / `removeFromPluginsPbxGroup`
* `addToResourcesPbxGroup` / `removeFromResourcesPbxGroup`
* `addToFrameworksPbxGroup` / `removeFromFrameworksPbxGroup`
* `addToProductsPbxGroup` / `removeFromProductsPbxGroup`
which are used internally in:
* `addPluginFile` / `removePluginFile`
* `addResourceFile` / `removeResourceFile`
* `addProductFile` / `removeProductFile`
* `addFramework` / `removeFramework`
But neither of these methods do a check whether the `PbxGroup` actually
exists before trying to modify it - this can result in a possible
null-access error.
I ran into this problem when trying to add a framework to a project
which didn't have a `Frameworks` `PbxGroup`
(related: transistorsoft/react-native-background-fetch#30).
This commit adds checks to these methods to test for existence of the
`PbxGroup`s and creates them if they don't exist or does an early exit
in the case of removal.
