Safe-navigation operator fails when operand is a property

[thomasfanell]

Here is a mock-up that should illustrate what I mean:

Polynomial: class {
    m_derivative: Polynomial
    derivative ::= this m_derivative
    init: func
}

somePolynomial := Polynomial new()
thirdDerivative: Polynomial

// error: 'source_Main__Polynomial' has no member named 'derivative'
thirdDerivative = somePolynomial $ derivative $ derivative $ derivative

// This works as expected
thirdDerivative = somePolynomial $ m_derivative $ m_derivative $ m_derivative

What appears to be happening is that only the outermost property access is translated to a call.
Probably a VariableAccess bug, SafeNavigation seems to be completely fine to me (all it does is make a huge ternary with accesses and checks to NULL).

On it.
