We missed a couple directories with previous attempts to turn this on globally: app/ and libtextsecure/ Not to mention files in places we didn't expect: ts files that weren't in the ts directory! This turns prettier on for every file we care about (js, ts, tsx, md) everywhere in the project but for a few key parts.
