unsatisfied expectation terminates suite

When mockery expectations fail, the currently running suite terminates because of exception thrown. I think the good solution would be to catch `Mockery\Exception\*` and fail the current test only.

Tell me how to fail the current test from the place where `Mockery::close()` is called and I'll prepare a pull request. `\Codeception\Module::fail()` terminates the suite completely?
