Fix Travis SYMFONY_REQUIRE config

The `composer install` script was running in `before_install`, while the `SYMFONY_REQUIRE` + symfony/flex was configured in `install`. Swapping these two from position fixes the Travis setup. (flex has to be configured before `composer install`).

I also removed `if ! [ -v "$DEPENDENCIES" ]; then composer require --no-update ${DEPENDENCIES}; fi;`, it seems to be a left over from previously used configs as the `DEPENDENCIES` is not defined anywhere.
