When building a config stack, stop SiteSource objects from poisoning the cache

Browse source 
Summary:
Ref T13168. I'm not sure how this worked before, but I ran into this issue on my new laptop.

SiteSource accesses `PhabrictatorEnv::getEnvConfig('phabricator.base-uri')` when local, which may poison the cache and lock the value since we don't later discard the cache.

Specifically, when I access `http://locala.phacility.com`, I was getting an error like "You made a request for locala.phacility.com, but no configured site can serve this request.". This was because the base-uri was being incorrectly frozen as "local.phacility.com". The expectation is that it will match, so the standard PlatformSite will serve the request.

Test Plan:
  - Before change: "no configured site" error.
  - After change: local instance works properly.
