Whose to say Javik was the only prothean left? The Prothean Empire spanned the galaxy, its more than possible that more survived. The Zha'Til being machines could've just lied down in minimum functioning for 50,000 years. The Oravores could have stasis technology similar to the Protheans, so they could have had a few make it into cryo-sleep.
