Unresolved reference when compiling with JS IR backend

If importing kodein-di version 7.3.1 or 7.4.0-master-113 and targetting JS with new IR compilation backend, the compiler errors with Unresolved reference: kodein.

The compiler do not find any reference to Kodein at all!

Due to a bug in the Kotlin JS IR compiler before 1.4.30, Kodein-DI is not compatible with Kotlin IR compilers before 1.4.30.

In commit 3c825ea, the Kotlin version used by the project is defined by Gradle, rather than by the property set in the gradle.properties file. The project is therefore compiled with Kotlin 1.4.21, but uses Kotlin-stdlib 1.4.30 (hence the warnings we can see int the build log).

Setting the Kotlin version manually in buildSrc/build.gradle.kts to 1.4.30 fixes the issue and allows kotlingram to build correctly.

plugins {
    `kotlin-dsl`
    kotlin("jvm") version "1.4.30"
}

Somehow using js(BOTH) was misconfiguring the task graph and task :api:core:generateTelegramApi was not being executed before :api:core:compilekotlinJsIr. Fixed with commit 3c825ea.

Now the bug should be reproducible always.
