Allow schemeless ip address as job url

When creating a Mojo::URL object without a schema, the whole
string is seen as a path, so it for 10.20.30.40/tests/42 it would be
a path with three elements '10.20.30.40', 'tests', '42'. Then the
first item containing a digit is taken as a match for the job id.

    use Mojo::URL;
    use Data::Dumper;
    my $url = Mojo::URL->new("10.20.30.40/x/y");
    say Dumper $url;
    __END__
    $VAR1 = bless( {
                     'path' => bless( {
                                        'trailing_slash' => '',
                                        'parts' => [
                                                     '10.20.30.40',
                                                     'x',
                                                     'y'
                                                   ],
                                        'leading_slash' => '',
                                        'charset' => 'UTF-8'
                                      }, 'Mojo::Path' )
                   }, 'Mojo::URL' );
