fix: correct handling of removed targets (#9824)

# Which Problems Are Solved

In Actions v2, if a target is removed, which is still used in an
execution, the target is still listed when list executions.

# How the Problems Are Solved

Removed targets are now also removed from the executions.

# Additional Changes

To be sure the list executions include a check if the target is still
existing.

# Additional Context

None
