Remove UnnecessarySafeCall safeguard against ErrorType

[cortinico]

Opening this to recall to remove this extra patch introduced in #3419
A fix was pushed upstream in the Kotlin compiler and should land in Kotlin 1.5

As soon as we bump the compiler-embeddable version we can also merge this PR (as the tests should be green)

We should be able to unblock this now, right?

Seems like the change didn't make to 1.5.0:
https://github.com/JetBrains/kotlin/blob/e73e039e43d740b890eaa4d7256362eeaf6ff1f7/compiler/frontend/src/org/jetbrains/kotlin/resolve/calls/CallExpressionResolver.kt#L542-L544

But is on master:
https://github.com/JetBrains/kotlin/blob/23faacd21b84af32921ecad785c8d30f1b930c34/compiler/frontend/src/org/jetbrains/kotlin/resolve/calls/CallExpressionResolver.kt#L545-L547

So we will probably have to wait a bit more

Kotlin compiler fix is included in 1.5.20-M1, so we should be unblocked by then.

Ooops sorry I misclicked the button.

I checked out this branch, rebased on main & ran a full build, so this just needs a rebase to check the CI passes on all platforms then it can be merged for 1.18.1 or 1.19.0.
