Fix scroll to quoted message

[mbarashkov]

This pull request fixes issue #566 by calculating the proper index of message that we want to go to, substracting number of additional album-contained messages from it.

Hi @mbarashkov, thanks for the PR!

It may be easier to just ask the proxy model for the id without any c++ changes, because that is the model for chatView:

            var proxyIndex = chatProxyModel.mapRowFromSource(index, -1);
            if(proxyIndex !== -1) {
                chatPage.messageIdToScrollTo = "";
                chatView.scrollToIndex(proxyIndex);
                navigatedTo(proxyIndex);
            }

Or did you try that and it didn't work?

cheers

@jgibbon
I just tried it, and mapRowFromSource doesn't seem to work correctly in a very simple test.
Actually this method just infinitely loops.

Hm, weird.
If I'm not mistaken that should be exactly what it's intended for – in that case there could be another bug… I'll have another look at this.
