Eric Stern 739881a3f4 Print a more useful error message if any PHPUnit tests crash
Summary:
Before, if PHPUnit crashed (syntax error, undefined constant, etc), you would get a relatively unhelpful error message:

    firehed@Eric-Sterns-Mac-Pro ~/dev/php-lcd: arc unit
    Exception
    Clover coverage XML report file is empty, it probably means that phpunit failed to run tests. Try running arc unit with --trace option and then run generated phpunit command yourself, you might get the answer.
    (Run with --trace for a full exception trace.)

This now checks the json and code coverage reports and tries to pull a useful error message:

  firehed@Eric-Sterns-Mac-Pro ~/dev/php-lcd: arc unit
  Exception
  The test '/Users/firehed/dev/php-lcd/tests/PlateButtonsTest.php' crashed with the following output:

  Fatal error: Undefined class constant 'EFT' in /Users/firehed/dev/php-lcd/tests/PlateButtonsTest.php on line 25

  (Run with --trace for a full exception trace.)

Or if nothing was written to `stderr`, you may get something like this:

  firehed@Eric-Sterns-Mac-Pro ~/dev/php-lcd: arc unit --no-coverage
  Exception
  Test Firehed\PlateButtonsTest::testSingleButtonOnButtonDown did not finish
  (Run with --trace for a full exception trace.)

Test Plan:
`arc unit` for arcanist itself
`arc unit` before and after the change on a project where:
* all tests pass
* some tests are failing
* a test causes a fatal error (undefined constant, bad method call, etc)
* a test file is invalid (syntax error)

No regressions that I could find, and all crashes now display a more useful error.
