Though defaultMultipleSelection is true still multiple selection is not enabled

[saurabhbajajcode]

Describe the bug
When we set YPImagePickerConfiguration().library.defaultMultipleSelection = true still multiple selection is not enabled by default.

To Reproduce
Steps to reproduce the behavior:

1. Create YPImagePicker object. You can use following code:

@IBAction func uploadImageTapped(_ sender: Any) {
        var config = YPImagePickerConfiguration()
        config.library.mediaType = .photo
        config.showsPhotoFilters = false
        config.shouldSaveNewPicturesToAlbum = false
        config.startOnScreen = .library
        config.screens = [.library, .photo]
        config.showsCrop = .none
        config.wordings.libraryTitle = "Gallery"
        config.hidesStatusBar = false
        config.hidesBottomBar = false
        config.maxCameraZoomFactor = 2.0
        config.library.maxNumberOfItems = allowedMaxTotalImages
        config.gallery.hidesRemoveButton = false
        config.library.preselectedItems = selectedYPMediaItems
        config.library.skipSelectionsGallery = true
        config.library.defaultMultipleSelection = true

        let picker = YPImagePicker(configuration: config)
        picker.didFinishPicking { [unowned picker] items, cancelled in
            if cancelled {
                picker.dismiss(animated: true, completion: nil)
                return
            }
            self.selectedYPMediaItems = items
            self.removeAllButton.isHidden = self.selectedYPMediaItems.isEmpty
            self.setNextButtonTitleForImageViewScreen()
            picker.dismiss(animated: true, completion: nil)
        }
        present(picker, animated: true, completion: nil)
 }

2. Call above function on tap of a button
3. Select only 1 image. Tap Next.
4. Again open image picker.
5. When image picker is displayed you will observe that multiple selection is not enabled even though defaultMultipleSelection was set as true. Also, the previous selected image is not highlighted.
   Refer attached gif.

Expected behavior
When defaultMultipleSelection is set as true then multiple selection should get enabled irrespective of number of items previously selected.

Screenshots
This screenshot and gif is after setting defaultMultipleSelection as true.

Hi @saurabhbajajcode,
Thank you so much for noticing that, documenting it thoroughly with video gif (amazing!) and issuing a clean PR that fixes it.
This is really splendid !

@s4cha shall we close this, once it's already merged?

Yep, this should be fixed as of 4.3.0 and coming 4.3.1 :)
