Function names with an underscore are not working properly.

[viggy28]

I had a function which has an underscore in its name and it didn't work as expected. Then i tested with a very simple function and it worked. I noticed there is an underscore in the actual function and that's the reason it wasn't working. Correct me if I am wrong.

Environment details

• OS: macOS Sierra 10.12.3
• Node.js version: 8.9.1
• npm version: 5.5.1
• @google-cloud/functions-emulator version: Don't know how to find that.

Steps to reproduce

1. Create a simple function with no underscore on its name. Invoke it. Should work fine.
2. Change the same name of the function to include an underscore, invoke it. It should still look for the old function name.

Thanks!
