The ldes:eventSource stays unchanged

Expected result The ldes:eventSource should be changed to the new configured version based one.

P.S. is it possible to configure two kinds of retention policies on the ldes:eventSource ? if yes=> please provide an example

Thanks

@xdxxxdx we'll need to validate this, but have you excluded the chance of a caching issue?

On verificiation, I saw that you posted to a non-existing collection (berab instead of bearb), however, this returns a 200 HTTP status, instead of an expected 404 status, but this will be fixed in #1427
