Coverage decreased (-0.2%) to 97.003% - you should provide tests for this :)

@dopesong

I added a test coverage for PHP7 only.

I do not know how to do better as far as Throwable appeared in PHP7.

As far as the coverage is performed in PHP5 and following the documentation http://php.net/manual/en/language.errors.php7.php#119652, the catch (Throwable $t) code is never reached in PHP5

try
{
   // Code that may throw an Exception or Error.
}
catch (Throwable $t)
{
   // Executed only in PHP 7, will not match in PHP 5
}
catch (Exception $e)
{
   // Executed only in PHP 5, will not be reached in PHP 7
}

Therefore I added @codeCoverageIgnore statement
