Incremental changelog won't count up timestamp or won't use the current timestamp but always the creation timestamp leading to incorrectly overwritten changelog files

[OmarHawk]

Overview of the issue

We do have an issue with incremental changelog generation, since v8. We have an existing application with a defined jdl, modify the jdl and let the jhipster jdl jdl.jdl command run. The problem is, it will always use the creationTimeStamp for file names as prefix for the changelog files and for changelog ids, therefore, two consecutive updates to the very same entity will override each other and you need to manually do something about it, or your liquibase changelog will break. In previous versions (7.9.3), the current timestamp was used instead, so everytime the jdl command was run, a completely new set of files was produced.

Motivation for or Use Case

Shouldn't have to manually fix something over the application lifecycle.

Reproduce the error

1. Create a basic application.
2. Generate an initial schema using jhipster jdl jdl.jdl --incremental-changelog command for incremental changelogs
3. Change an entity in the jdl (remove a field) and let the jhipster jdl jdl.jdl command run again
4. Change the same entity again (add a field) and let the jhipster jdl jdl.jdl command run again and see that JHipster tries to override the already existing (and possibly already applied to database) file

You can see the last step in the following screenshots. Here, the last step is visible, and JHipster tried to override the already existing update file: This is the file content before JHipster does so: And this is after JHipster has done so:
