IR: fix SAM conversion for types with contravariant intersection argument type

Browse Source 
In the added test, the problem was that the SAM type as computed by
`SamTypeFactory.createByValueParameter` was `Consumer<{BaseClass &
BaseInterface}>`, which was latter approximated in psi2ir during the
KotlinType->IrType conversion to `Consumer<out Any?>` (here:
https://github.com/JetBrains/kotlin/blob/3034d9d791cf1f9033104e12448e0d262d3bc3ce/compiler/ir/ir.psi2ir/src/org/jetbrains/kotlin/psi2ir/generators/ArgumentsGenerationUtils.kt#L606),
because intersection type argument is approximated to `out Any?`.

To avoid this, replace intersection type in immediate arguments of a SAM
type with the common supertype of its components at the same place where
we're getting rid of projections.
