FIX avoid from re-initializing result on nested hook getEntity

• when you have a first hook such as "formBuilddocOptions" calling "getEntity()" function
• then "getEntity()" function executes the hook "hookGetEntity" (nested hook) and results of the previous hook are re-initialized

For example
We have two module : Module 1 and Module 2

1. Module 1 : hook "formBuilddocOptions" is adding some (using "resPrint" of hook manager object)
2. Module 2 : hook "formBuilddocOptions" is calling getEntity() and then the global "hookmanager" is re-initialized and "resPrint" value is now empty
3. So the options before generating a document are lost (resPrint is empty)

@eldy
You're right. It's a better way to resolve this problem of nested hooks.

Could you check why I have this Travis error ?

• Checking PHP syntax errors (only 1 version to not overload travis and avoid duplicate tests)
• parallel-lint: command not found
