Undefined variable after recent update

[jakereps]

Hey 👋! I recently updated this plugin, and am experiencing an error when trying to generate tests - seemingly related to this change. I'm not sure if this is a bug, or if there's something I need to do on my end to fix it to be able to generate tests now.

Error in nvim:

Error detected while processing function gotests#alltests:                                                                                                                                            │

I've tried modifying locally to change the newly introduced tabs to spaces to see if that helped (as the entire file uses spaces except for the 4 new lines now use tabs), but it didn't seem to change the outcome.

Figured it out, and the changes work locally - PR with a fix submitted 👍
