- if we enable warning logs in E2E tests, we get a bunch of error
messages saying `ERROR Unhandled rejection: aborted` coming from the
SQLite DB reset code
- specifically, it's coming from the line that resets the DB by copying
the file
- this line was initially added because we would see random SQLite
"malformed database" errors
- I have a feeling that was due to something else, but I can't be sure
- I'm also not sure how else we should shut the DB connection, as this
is the recommended way but it throws an unhandled rejection
- this commit is a bit of a gamble because I'm not actually sure what
was causing the problem, but it gets rid of the errors locally and
doesn't regress on the random failures
- we've had an optimization in CI that copies a fresh SQLite DB to a
file, and copies it back when we need to do a DB reset
- I originally only let this run in CI but we've had it around for a
while so we should GA it to run on local machines
- there may be edge cases, but we should fix them instead of letting
tests run slower for development
- this also makes sure we clean up any existing files before
initializing the DB

- this commit turns the Ghost repo into a monorepo so we can bring our
internal packages back in, which makes life easier when working on
Ghost
