Convert simple_form input using wrapper_options

[steveyken]

Reading heartcombo/simple_form#997 we need to update our simple form field updates from

def input

to

def input(wrapper_options)

and then can use

text = @builder.text_field(field.name, merge_wrapper_options(input_html_options, wrapper_options))

instead of

text = @builder.text_field(field.name, input_html_options)
