Duplicate teams are created for the same Jira board.

Issue Summary

Duplicate teams are created for the same Jira board.
The synchronization of teams occurs only within Jira Board's Time interval, and there is a check (in agileCraft.CreateACTeam method) of whether the Team exists or not to avoid duplication(to create/update). But if it fails on this action due to a SQL connection issue, it returns an empty Team object and updates the board with AgileCraftTeamID=0. Then on the next loop, it will create a new Team for that board.

Steps to Reproduce

The issue is difficult to reproduce on demand, it happens when a connection to the database fails during the check of the existence of Teams for the board.

Expected Results

It is not allowed to have duplicate team names.
It should create one team per board.

Actual Results

Two teams with the same name are created

Workaround

Rename one of the duplicate teams and then delete it.
