fix(projections): added check to make sure there cannot be 2 projections for the same table (#10439)

# Which Problems Are Solved

It should not be possible to start 2 projections with the same name.

If this happens, it can cause issues with the event store such as events
being skipped/unprocessed and can be very hard/time-consuming to
diagnose.

# How the Problems Are Solved

A check was added to make sure no 2 projections have the same table
