Consider the following example from
`extensionLambdasAndArrow.kt`:
```
val x4: String.() -> String = if (true) {
{ str: String -> "this" }
} else {
{ str: String -> "this" }
}
```
Because of
`coerceFirstParameterToExtensionReceiver`
the given lambdas must be of the type
`String.() -> String`, but because of a bug
they are `String.(String) -> String`. At the
same time, during inference their expected
types are, indeed, calculated correctly as
`String.() -> String`.
