Subject: [PATCH] test(examples): give each run its own sqlite database

The test profile pointed at ./test.db in the app directory, so a run inherited
whatever schema an earlier run left behind. On a machine with a stale file,
0003_add_password re-applied ALTER TABLE ADD COLUMN over a column that already
existed; fail-on-test-warnings turned the warning into a failure, and
check:production failed for environment reasons rather than code.

Each run now uses a fresh database under the OS temp directory. Verified by
restoring the stale dev.db and test.db that reproduced the failure: the suite
passes with them present.
