Subject: Move html_safe declaration for user_mailer from layout to helper
X-Git-Tag: live~31
X-Git-Url: https://git.openstreetmap.org./rails.git/commitdiff_plain/ce342fede0fc465993e588487056d76458f97169

Move html_safe declaration for user_mailer from layout to helper

This allows us to enable output safety checks for all code within
erb files.

`rubocop --auto-gen-config` ignores code within the erb files, so
it is easier to maintain an exclusion on the helper than inside
the layout.
