2.8 composer.json depends on unavailable Polyfill packages #16363
Description
2.8 composer.json contains:
...
"symfony/polyfill-intl-icu": "~1.0",
"symfony/polyfill-mbstring": "~1.0",
"symfony/polyfill-php54": "~1.0",
"symfony/polyfill-php55": "~1.0",
"symfony/polyfill-php56": "~1.0",
"symfony/polyfill-php70": "~1.0",
"symfony/polyfill-util": "~1.0"
...
But there is no 1.0 tag on any of them so composer fails to update.
Composer error message: symfony/symfony 2.8.x-dev requires symfony/polyfill-intl-icu ~1.0 -> no matching package found.
