* fix a bug in query builder where tables are sorted randomly

Call createFilesForSecurity() manually  in the update (doing this on cache delete affects IO performance too much in development mode)

This is related to https://forum.piwik.org/t/license-missing-of-a-free-glp-plugin/21674 

Some users see a license warning for a free GPL plugin. I have spent hours trying to understand how this could possibly happen over the last weeks but not sure how it happens. It must be some kind of caching issue with a certain PHP version or something. This change might not fix the actual issue but is a good check to have on top to check for invalid licenses only if it is not a free plugin.
