Description of problem:
`gio open` launches Chromium browser when opening a file through ftp instead of a associated file handler application.

Version-Release number of selected component (if applicable):
glib2.x86_64        2.68.1-1.fc34
nautilus.i686       40.0-1.fc34
chromium.x86_64     89.0.4389.90-3.fc34

How reproducible: Can be reproduced with F34 Live media.

Steps to Reproduce:
1. Boot VM with Fedora 34 live.
2. Open FTP share with Nautilus.
3. Open directory in terminal from Nautilus's context menu.
5. Run `gio open <file>`. Result will be as expected, Application associated with file type will pop-up.
6. Install Chromium browser.
6. Run `gio open <file>`. Now gio launches Chromium instead.

Actual results:
gio opens file with Chromium browser with `file:///run/user/1000/gvfs/ftp:host=host/dir/file` in addressbar.

Expected results:
gio should open files with a file handler, just like with no Chromium installed.

Additional info:
gvfs mounted directory `/run/user/1000/gvfs/ftp:host=servak.local/Куча`
