[HttpKernel] Fixes AppCache + ESI + Stopwatch problem

There is a very special case when using builtin AppCache class as kernel wrapper, in the case of an ESI request leading to a `stale` response [B]  inside a `fresh` cached response [A]. In this case, `$token` contains the [B] debug token, but the  open `stopwatch` section ID is equal to the [A] debug token. Trying to reopen section with the [B] token throws an exception which must be caught.

I tried to find a better solution than just wrapping thrown exceptions with `try/catch`, but IMHO the #6230 solution from @lsmith77 was in fine the best one. I just added some comments in the code to avoid the WTF reactions while reading it.

@vicb never agrees :)

I don't have time to check this deeply now but I would like to see a UT.

Could your use case be expressed as "on nested terminate events" ?

@vicb If I had an idea on how to write a conclusive test for that, I swear, it would be provided in this PR.

I ran into this when somewhere in our code the Response object was cast into a string. After that, when send()'ing the Response, the headers would be all mixed up. This is because the __toString in HeaderBag ksorts the headers, while the __toString in ResponseHeaderBag doesn't ksort the corresponding headerNames. This patch ksorts that one as well.

allPreserveCase() is new to 2.2, so this bug doesn't seem to affect earlier versions.

To be exact, this is where it got introduced: https://github.com/symfony/symfony/commit/63a228c45613bb

B.t.w. another option was to ksort a copy of the headers array in the ResponseBag and leaving the actual thing as-is. Not sure which one would be the best option?

Fixed handling absent href attribute in base tag

The HTML5 spec states that the href attribute is optional for the
base tag. Fixed the DomCrawler::addHtmlContent() method to support this
