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

arbre/lib/arbre/element.rb

Line 175 in 4d5858d

def method_missing(name, *args, &block)

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