core.moduleapi: Fix :context() called from a global module Because `is_global` defaults to nil, it passes trough the metatabele to the calling module, so a host context retrieved from a global module would have the .global flag be true. This causes trouble with the code retrieving the hostname in `module:http_url()`, so `http:list()` in the shell would produce host URLs like `https://*:5281/`
