Fix TranslationHelper#translate handling of Hash defaults

It is sometimes expected of the `translate` methods to return a Hash,
for instance it's the case of the `number.format` key.

As such users might need to specify a Hash default, e.g.

`translate(:'some.format', default: { separator: '.', delimiter: ',' })`.

This works as expected with the `I18n.translate` methods,
however `TranslationHelper#translate` apply `Array()` on the default value.

As a result the default value end up as `[:separator, '.', :delimiter, ',']`.
