Unclear which remote will be used when installing from list views

## What Happened

I have Flathub added as a user remote, so I went to install GIMP from a search result view. It installed, but then showed up as a beta version. Apparently it installed from `chrome-origin` remote, which exists because I installed a beta version of Chrome from Flathub.

## Expected Behavior

AppCenter should either prefer Flathub, or if we don't want to have preferential treatment, we should probably just ask with a dialog when it’s unclear which version should be installed.

## Steps to Reproduce

1. Have an app available in multiple third-party origins
2. Search for that app
3. Install that app from the search list
4. Try and guess which remote it'll be installed from

## Platform Information

OS 6 Odin stable
