Using memory jugglingdb adapter forces opt-in to re-registering on startup and deregistering on shutdown. no-dereg changed to force-dereg.

As a followup to the registration logic changes I made in #35, this PR fixes what I broke ;)

The issue is that if you're using the JugglingDB memory adapter, you most certainly want to be forcing registration and de-registration whenever the app starts up and shuts down. Once you use any kind of store that persists between restarts, you almost always want to use the logic I added in #35. This PR changes no-dereg AC_OPT to instead be force-dereg, and brute-force adds force-dereg + force-reg to process.env.AC_OPTS, if the JugglingDB store is memory.

FWIW, I looked into making the sqlite3 adapter the default for ACE apps, but I had to raise this PR as the sqlite3 adapter doesn't actually support Schema.JSON, which we're using. What a mess! Once that PR is merged upstream I'd like to propose that we make sqlite3 the default store for ACE apps.
