Arbre::Element method_missing gives precedence to assigns instead of helpers

[awaismbajwa]

I am facing this issue where I need to access current_user method that is returning different value as compared to @current_user.

in erb templates current_user helper method is invoked as expected and does the job as intended.

but in arb templates @current_user gets precedence through assigns array as it is coded here https://github.com/activeadmin/arbre/blob/4d5858d9ffb44e018e5bebf223a81c742b144693/lib/arbre/element.rb#L175

should not helper methods be getting precedence? as it is in erb templates also
