Set passphrase before reset account for kitchensync.

There are some e2e tests which set passphrase. After they run, we can
not reset account because we can not start sync. With this change, account
can correctly sign in after those tests, no matter the account requires
or not the passphrase.

TEST: tested e2e tests can still pass.
