clientlib.css not refreshed when child .css files are being deployed

(originally reported by @eglistefan)

In the aem-project-archetype we have a sample clientlib. That one causes problems lately, namely the clientlib.css remains empty.

When adding an unrelated property to /etc/designs/myapp/clientlib, the clientlib mechanism (ie HtmlLibraryManagerImpl) seems to be correctly triggered and the clientlib.css is refreshed properly.

What is likely happening is this:

• eclipse starts deploying the ui.apps project (of the archetype)
• it eventually deploys /etc/designs/myapp/clientlib, and clientlib/css.txt
• this seems to trigger the clientlib.css to be generated
• few seconds later only, it deploys the child nodes, eg clientlib/css/main.css
  • that seems to be missed by the HtmlLibraryManagerImpl
  • and thus the originally generated, empty, clientlib.css stays in the cache

I am no longer able to reproduce this ; with a sample project built from the 11-SNAPSHOT version of the archetype after deploying the .apps and .content projects the http://localhost:4502/etc/designs/test/clientlib-all.css is correctly rendered.
