Metrics/LineLength: Line is too long.
RSpec/InstanceVariable: Use let instead of an instance variable.
Layout/TrailingBlankLines: Final newline missing.
Style/StringLiterals: Prefer double-quoted strings.
Maintain the method for models that are still translatable. This help
me to pass the CI build. In later PR's this method will be eliminated
as no one will invoke it.
Move method from sanitizable to globalizable concern because
globalize_accessors were overiding sanitizable method and was never
called. Another solution to this could be to load sanitizable
always after globalizable concern.
Old method implementation was not working well with globalize_accessors,
it was returning nil always.
