Corner case for get_language_for_request function in translation

[Ramiro Morales]

As I understand the problem would show itself if the following, rather strange, conditions are met:

• User language preference specify xx-YY
• xx_YY l10n is supported by the Django installation (i.e. it's listed in settings.LANGUAGE)
• The actual xx_YY/LC_MESSAGES/django.mo is missing from the project, or the Django installation itself
• xx is listed in in settings.LANGUAGE
• xx/LC_MESSAGES/django.mo file exists

In this scenario, Django won't use the xx translation.

PS: Also, pyflakes points out there is an unused import of settings in line 61 of the same file.

(In [8606]) Fixed #8584 -- Fixed a case where the wrong locale might be made active in the
locale detection loop. Thanks, Ramiro Morales.
