Feature/merge smarty-phpunit into tests subfolder (#580)

* Removed unneeded files and replace dummy.txt with .gitignore files
* Synced unit tests with master codebase, noted TODO's, fixed phpunit scripts and travis config
* fix php7.4 deprecation and remove php7.4 from travis allow_failures since php7.4 is current stable
