Some QR Code scanners don't respect custom schemes like fdroidrepo://, so this is a workaround, since the local repo URI is all uppercase in the QR Code for sending the local repo to another device. This way, the QR Code can still be all uppercase and use HTTP:// and Android will still route it to FDroid, but via the Just Once/Always chooser (fdroidrepo:// goes directly to FDroid with no prompt, when it works)
