faker helper behavior is to stringify arrays and objects.
Considering the recent improvements to helpers in general (avoiding stringifying to maximize compatibility between helpers) this should be changed.

Multiple possibilities:

• add a new helper fakerRaw not stringifying the results.
• add a new param (named) if possible.
• remove the stringify. This would cause a breaking change which impact should be assessed.
