Fixed bug - Motech does not start after building all projects

https://trello.com/c/UO5VCwzf

org.eclipse.osgi-3.6.0.v20100517.jar was causing LinkageError. However, the
demo bundle was not using the jar. Hence excluded the jar from the dependencies.
BUG: Remove creating motech user from web-security build process.

https://trello.com/c/wF5PQdfd

Each module that needs motech user for IT should create the user before IT
and deletes the websecurity db after IT. Demo Bundle IT requires motech
user. So, added the pre and post IT goals.
