[Flight] Unwrap lazy before reading the value (#30938)

This is important if the lazy is at the root of the chunk. I don't have
a unit test for it but @gnoff has a repro.

It also shouldn't unwrap the last value since that's the one we're
referencing.

This was already done correctly by @unstubbable in waitForReference so
this just aligns with that.
