Minor Docker image enhancements

Minor update to docker build

Better Error Messages and individual locks per-user

A database change exists, hence the version change. It's only an index change so you can drop the existing one and create a new one:

Old Index on Timeblock table:
["startTime", "trackedtaskId"]

New Index on Timeblock table:
["startTime", "trackedtaskId", "userId"]
