Support suppressing errors

[rokoroku]

With async translation resources, my console is messed up with console.error from [React Intl] ... while testing.
I couldn't find any options to suppress these errors. The code is saying process.env.NODE_ENV === 'production' , but it doesn't make sense during testing process.

Could you support this feature?

I found that this issue is duplicated (#619), but it is really required feature.

Do you have locale and defaultLocale props set to the same value on your <IntlProvider>?

I want to test this scenario :

<IntlProvider locale={browserLocale} defaultLocale={defaultLocale}>
    ...
</IntlProvider>

I can get browser's locale from navigator.language, but sometimes it returns undefined depends on browsers.

So you want to say, if browserLocale is null, we need to set it as defaultLocale like this?

<IntlProvider
        locale={locale || defaultLocale}
        defaultLocale={defaultLocale}
        messages={translation[locale || defaultLocale]}>
    ...
</IntlProvider>

Then what's the purpose of prop defaultLocale ? What does it exist for?

[ericf]

defaultLocale exists to signal what locale your app's default messages are written in. It's used as the fallback locale in case something went wrong with loading locale data. In the case where your locale and defaultLocale are the same — which would be the case when testing, then errors will be suppressed. But when locale and defaultLocale are different, then the intention is to warn about missing message translations.

Okay, sorry for late reply.
I updated my test code like above. This is maybe only needs for our test environment, and not an critical issue. So I close this issue :)
