Title: Check URI scheme for src attributes

Me again... This time with a bugfix.

> As of version 1.0.3, URI scheme checking is performed on all href and src tag attributes.

"src" attributes are not being checked:

```perl
my $hr = HTML::Restrict->new(
rules => {
a => [qw( href )],
img => [qw( src )],
},
);

$hr->set_uri_schemes( [ undef, 'http', 'https' ] );

say $hr->process('click here');
# click here

say $hr->process('');
#
```
