Code Issues Proposed changes

Run the db migration tests in the same test worker 

In a heavily IO deprived CI VM the db migration tests could take a
significant amount of time and eventually time out. This patch moves the
tests into the same test executor worker process to spread the load
generated by these test in time until a final solution is found. For
example we hope that [1] will help eventually to decrease the load.
