fix: add current state for execution handler into setup (#9863)

# Which Problems Are Solved

The execution handler projection handles all events to check if an
execution has to be provided to the worker to execute.
In this logic all events would be processed from the beginning which is
not necessary.

# How the Problems Are Solved

Add the current state to the execution handler projection, to avoid
processing all existing events.

# Additional Changes

Add custom configuration to the default, so that the transactions are
limited to some events.

# Additional Context

None
