Re-instate the Bootstrap class

This simplifies the binary and makes it possible for phing to
use it again.

Updated Mockery

Mockery was still breaking on PHP 5.5.12 with the unserialize errors introduced during that fiasco.
This should now run on any setup.
Avoiding assertTrue(true)

Turned the "useless test" flag off since we are using mockery which led us to use a lot of $this->assertTrue(true) to avoid
phpunit strict errors.
Dropped the current ones spread out in the tests and made the change to the dist file.
