Instruct Awaitility to ignore exceptions that occur during evaluation and matches the supplied Hamcrest matcher.
Exceptions will be treated as evaluating to
<code>false</code>. This is useful in situations where the evaluated conditions may temporarily throw exceptions.

@return the condition factory.
