possible incompatibility with the gatlin plugin

[corbym]

Firstly, thanks for some excellent libraries, very useful!

There seems to be an incompatibility with the gatlin plugin:

To replicate:

• be me
• have a project with a gatling plugin and some gatling tests in the gatling module
• also have a kotlin main module
• project also uses the kapshot plugin

plugins {
   id("io.koalaql.kapshot-plugin") version "0.1.2"
}

• mfw try to run the gatling tests using gradlew gatlingRun

I haven't looked too deeply at the issue, but it seems to me this could be easily fixed by not using first and using firstOrNull where the generator is trying to, er, generate.
