[BUG]: Incorrect default value of Phalcon\Annotations\Annotation properties

[sergeyklay]

The following properties of the Phalcon\Annotations\Annotation are declared as NULL:

cphalcon/phalcon/Annotations/Annotation.zep

Lines 18 to 23 in 923c378

	/**
	* Annotation Arguments
	*
	* @var array
	*/
	protected arguments;

cphalcon/phalcon/Annotations/Annotation.zep

Lines 25 to 30 in 923c378

	/**
	* Annotation ExprArguments
	*
	* @var string
	*/
	protected exprArguments;

However, their getters returns arrays:

cphalcon/phalcon/Annotations/Annotation.zep

Lines 87 to 90 in 923c378

	public function getArguments() -> array
	{
	return this->arguments;
	}

cphalcon/phalcon/Annotations/Annotation.zep

Lines 95 to 98 in 923c378

	public function getExprArguments() -> array
	{
	return this->exprArguments;
	}

This leads to a fatal error:

PHP Fatal error:
Return value of Phalcon\Annotations\Annotation::getArguments()
must be of the type array, null returned in Unknown on line 0

Also note that exprArguments annotated as a string, but this is wromg. This property should holds arrays only.

Also Phalcon\Annotations\Annotation::getArgument my return void:

cphalcon/phalcon/Annotations/Annotation.zep

Lines 75 to 82 in 1cd1da2

	public function getArgument(var position)
	{
	var argument;
	if fetch argument, this->arguments[position] {
	return argument;
	}
	}
