    placesview: Open location even if mount was not found
    
    Some locations have to be mounted, but their mounts are not user-visible
    (e.g. smb-browse). Though this is maybe a bit weird, it is how it works
    for years. The problem is that the commit 267ea755, which tries to get the
    default location for opening, caused regression as it doesn't expect such
    possibility. Before this commit, such locations were opened without any
    issue, but nothing happens currently after clicking to "Connect" except of
    clearing the "Connect to Server" entry. Let's fallback to the original
    location if the mount was not found to fix this regression.
