fix: don't remove groups by name as multiple can coexist

[rigor789]

Removing groups by name will remove valid groups in case there are multiple groups with the same name, ie. the same folder name as part of multiple different folders.

platforms/ios/src/
  Foo/
    Foo1_Files/
      Resources/ <bunch of images>
      Storyboard/
        Foo1.storyboard
    Foo2_Files/
      Resources/ <bunch of images>
      Storyboard/
        Foo2.storyboard

Foo1_Files/Resources and Foo1_Files/Storyboard would be removed causing these resources to be missing.
