Bug: getTableArgument does not work with PropAccessExpr

[sam-goodwin]

Moving to SWC introduced a regression with ReferenceExpr - the ts-transformer used to transform expressions such as PropAccessExpr into a ReferenceExpr if the root was pointing to a free variable.

const a;
() => {
  a.b; // used to be ReferenceExpr(() => a.b),
}

SWC made it so the ReferenceExpr only took the place of an Identiifer, i.e. in this case PropAccessExpr(ReferenceExpr(() => a), "b")

Upon updating the samples to SWC, the saga-function broke because getTableArgument assumes the previous behavior: https://github.com/functionless/functionless-samples/blob/main/packages/sagaFunction/src/saga-function.ts#L45

SynthError: First argument into putItem should be an input with a property 'Table' that is a Table.
