Title: [HttpKernel] Added UTF8 encoding, decoding to MongoDBProfilerStorage

Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes

It didn't take long for us to hit a non-utf8 error using the new `MongoDBProfilerStorage`. I'm pretty sure the culprit was the Switfmailer DataCollector serializing a message with a PDF attachment.

I thought this would be a good failsafe, although one could ask whether mail message attachments should be serialized at all...
