try to fix new php tests for open source

Summary:
This was a pretty bad import into open source :(

* date tests assumed PDT. I tried putting `date_default_timezone_set("America/Los_Angeles");`. Lets see if that helps.
* options test checked for `phpmcc` which is only a facebook thing
* I'm not sure what is wrong with hash or network, but their output totally masks the real value. Made the tests output their value so I can at least test in prod.

Test Plan:
will see what travis does wit this

Since all the tests passed before and all I was doing is moving the `.out` to `.expect` nothing should have changed
