Handle redirect not working in Dspace-CRIS 2023-02-04

[OrdinaryGitUser]

Describe the bug
When I visited the test site https://dspacecrisdemo.4science.cloud/home, I noticed that the links like https://dspacecris7.4science.cloud/handle/** in collection/community and item were not working. I get the error "No item found for the identifier handle:"

To Reproduce
Steps to reproduce the behavior:

1. Go to https://dspacecris-demo.4science.cloud.
2. Find any link like :https://dspacecris-demo.4science.cloud/handle/**.
3. Try following this link.

Expected behavior
The expected behaviour is to open the corresponding item or community/collection page at https://dspacecris-demo.4science.cloud/handle/** as it was in previous versions.

I can also confirm this bug's occurence in the DSpace-CRIS 2023.02.05 version, as my client reported that hdl.handle.net URLs were returning a 'No item found for the identifier' error. Upon further investigation, it looks like the issue comes from the IdentifierServiceFactory.getInstance() returning null.

I think this issue can be closed as the bug has been resolved in commit 57d4c8d (fixed in version DSpace-CRIS 2023.02.06)
