    dav: Fix crashes caused by extra unref
    
    The `mount_base` uri is unreffed twice. First time over the local `mount_base`
    pointer and for the second time over the `G_VFS_BACKEND_HTTP (backend)->mount_base`
    pointer. This leads to `SIGABRT` from the `__pthread_kill_implementation`
    function. Let's remove that extra unref to fix this crashes.
