Changed the implementation, token is filtered out in the class which is the source of the exception. So it is not leaked by neither inner nor outer exceptions.

There is a problem related with an unit test, I wrote the test to check inner exception message but std::rethrow_if_nested doesn't throw the inner exception. Added it to comment.

On application crash it is not printed to stdout. But the token is included nested_exception that's why I added filter handler to SyncHttpsRequest earlier.
