Inconsistency in how to run tests

[pbowyer]

The testing documentation consistently uses php ./vendor/bin/phpunit to invoke tests.

When I install symfony/test-pack it outputs:

$ composer require --dev symfony/test-pack
Using version ^1.0 for symfony/test-pack
./composer.json has been updated
[...]
 symfony/phpunit-bridge  instructions:

  * Write test cases in the tests/ folder
  * Use MakerBundle's make:test command as a shortcut!
  * Run the tests with php bin/phpunit

Run the tests with is inconsistent with the documented way. I make no judgement about which is right, but the two should match.

Happy to create a PR once I know which one to change.
