Title: Fix #283: throwExceptions ="false" but Is still an error

Altered conditions in the MustBeRethrown extension method.
Fixed relevant tests and added a new one.

I'm unsure of what to do with the `ConditionParseException`:

- should it be thrown even if `throwException="false"`?
- should it be sub-classed from `NLogConfigurationException` and swallowed as well?
