Title: eZSimplePrice::attributes() doesn't support any arg, but a call uses 1 arg => this arg is useless

In order to solve the problem, some lines have been cleaned as the $this->attributes is an array that already contains the eZSimplePrice::attributes (thanks to array_merge function)

so hasAttribute has no need to perform a check on eZSimplePrice::attributes, as a check on $this->attributes is sufficient
