1. Rhaenyra Targaryen was eaten by a dragon incited by her brother. Of course, immunity to fire would indicate she was eaten raw, contrary to a dragon's preference, but the dragon was coerced. Dragons should certainly be capable of this, and maybe they become less picky with maturity.

2. Even if Rhaenyra was not immune, with a sample of only two to judge by, it's just as likely that she, rather than Daenarys, was the unique one.
