knex/avoid-injections throws if file contains knex.schema.raw

[renarsvilnis]

Hi, I'm trying to use the plugin to test DB migration files that use knex.schema.raw(...). And the plugin fails and eslint doesn't execute further.

Looked into the avoid-injections.test.js file and saw that the rule don't cover that case at all.

Debugged a bit and found out it happens when I have settings.knex.builderName = ... set .eslintrc as that runs conditional code - https://github.com/AntonNiklasson/eslint-plugin-knex/blob/master/rules/avoid-injections.js#L19

Error message:

TypeError: Cannot read properties of undefined (reading 'name')
