ForceSimpleAmpersand is ignored

[Oliver Jusinger]

Steps to reproduce

1. CKEDITOR.config.forceSimpleAmpersand = true;
2. save an link with href=​http://www.foo.bar/?foo=bar&foo=bar
3. forceSimpleAmpersand is ignored

Expected result

href=​http://www.foo.bar/?foo=bar&foo=bar

Actual result

​http://www.foo.bar/?foo=bar&foo=bar

Other details (browser, OS, CKEditor version, installed plugins)

4.7.1 and earlier

Fix: htmlwriter/plugin.js move htmlEncodeAttr before forceSimpleAmpersand handling:

Diff:

> 				attValue = CKEDITOR.tools.htmlEncodeAttr( attValue );
184d184
< 				attValue = CKEDITOR.tools.htmlEncodeAttr( attValue );

(limited js and ckeditor knowledge, but the fix works for me)
