Add support for project isolation

[NikolayMetchev]

It would be good to get a head start on adding support for project isolation to this plugin.
Project isolation is documented here:
https://docs.gradle.org/current/userguide/isolated_projects.html

On my project I get the following problems currently:

- [error] Project `:services:auth:db:dao` cannot access `Project.group` functionality on another project `:utils:mapstruct:spi`
    - plugin 'io.github.schwarzit.lightsaber'
        - Exception at `schwarz.it.lightsaber.gradle.processors.ProcessorKt.isDaggerCompiler(Processor.kt:30)`
org.gradle.api.InvalidUserCodeException: Project ':services:auth:db:dao' cannot access 'Project.group' functionality on another project ':utils:mapstruct:spi'

I can't reproduce that error. Could you provide a sample project?
