PHP: fixed crash when calling module functions in OPcache preload.
In PHP, custom fastcgi_finish_request() and overloaded chdir() functions can be
invoked by an OPcache preloading script (it runs when php_module_startup() is
called in the app process setup handler). In this case, there was no runtime
context set so trying to access it caused a segmentation fault.
This closes #602 issue on GitHub.
