DB Store header is corrupt
When using Android emulator 27.3.9.0 with an API 28 Google APIs Intel x86 Atom System Image Revision 4 or 5, creating a new account after "forgetting the password" causes a `org.h2.jdbc.JdbcSQLException: Encryption error in file null` exception when reinstalling with Android Studio while still signed in.
