When running go-ts-mode-test-file, it seems to match things that aren't 
functions like interfaces. I think we should only be matching functions, and 
more specifically, shouldn't we only be matching functions starting with "Test"?
We could perhaps extend the error checking to include that as well?

For the commit message, I'm not sure we need that paragraph especially when 
it's already described in the news. Eli what do you think?

+*** New unit test commands.
+Two new commands are now available to run unit tests.
Three?

I'm also wondering if we should include "current" in the go-ts-mode-test-file 
and go-ts-mode-test-package function names. Maybe someone would expect that 
they would get prompted to select a file or package to test? Maybe I'm 
overthinking that :). Eli what do you think?
