Fix issue with SQlite connection

[alibell]

The current docker image doesn't work with SQLite.

There are two main issues :

• pcheck is executed even if the $CMD_DB_URL connection is configured to use an sqlite database
• the sqlite3 node package is not installed by default

The current fix resolve these two issues.

I was wondering why a migration was created to add an index in this PR? By the way, I’m very interested in the fix. Is the project still active?

Hi @alibell, Thanks for the PR. However, according to the description of the PR, I think the Revision migration script should be separated to another PR.
