copyAsIs on directory with html file still moves html file

[has-n]

Describe the bug
If copyAsIs is used for a directory with an html file inside it, the complete directory gets copied - as expected. At the same time, the html file inside the directory is put into the root of dist which is the default behavior - this is unexpected.

To Reproduce
Steps to reproduce the behavior:

1. create a directory "test" with an html page inside it "page.html"
2. add this to the build config: copyAsIs: ["test/*"]
3. note that dist/test contains page.html
4. there is also a processed version at dist/page.html

Expected behavior
Ignore *.html files when using copyAsIs command
