PdfReaderViewModel.update java.lang.NullPointerException

[Dima-Android]

The only way I was able to reproduce this crash is by quickly tapping various settings buttons in PdfSettingsScreen.
Each time a setting is changed it immediately affects the PdfScreen and makes the pspfkit’s pdfView to reinitialize (it has to reinitialize to apply new settings).
The fix for now is to make changing a setting to not trigger pdfView reinitialization immediately and instead wait until the point the PdfSettingsScreen is closed. This way user gets to select all the settings user wants to change, navigates back to PdfScreen and only then they get applied.

I will keep monitoring whether this crash disappears or whether there are other triggers.
