Two of 'em.
1/ This is not the Master as last seen taking down Rassilon. That was a half-alive, resurrected-from-genes-on-Lucy's-lips, undead monster version. The real Master - the one the Doctor 'left... for dead' (as mentioned in the episode) - was last seen on the Valiant. So Missy knows nothing about Gallifrey, Rassilon, or any of that. As far as she knows, the Doctor last met her 'refusing to regenerate' (yeah, like we ever believed that) after succeeding in conquering the Earth and being beaten by Jesus!Ten.
Another point in support of this: there's a statement in the wildly uncanonical Doctor Who: Unbound AUs that a Time Lord will regenerate into the opposite sex if they commit suicide. What else would you call a refusal to regenerate? ;)
2/ It's not the Master. Seriously, why do we believe anything she says? Rule One applies to other Time Lords, too. She's actually... yes, you guessed it, the same person every female character has been suspected of being since 2005... the Rani! After all, she's a scientist, while the Master definitely is not. And she knows of the Doctor's rivalry with the Master, which she would absolutely make use of. And, perhaps most significantly: Steven Moffat has specifically denied that he has any plans to bring back the Rani. ^-^
Oh, and one for luck (not Missy related):
3/ That face reflected in Pink's iPad in the last shot... we're supposed to think that's The Boy, I'm sure, but to me, it looked a lot like Lalla Ward... Romana's in the Nethersphere. ;)
