### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-devlake/issues?q=is%3Aissue) and found no similar issues. ### What happened When collecting development data from TAPD, the iteration type changelog in DevLake displays an incorrect value. Specifically, when the "from_value" or "to_value" fields are empty, the displayed value is something like `tapd:TapdIteration:2:0`, which is not the expected empty value. ### What do you expect to happen The expected behavior is that when the "from_value" or "to_value" fields are empty, the value displayed in DevLake for the TAPD iteration type changelog should be empty as well. ### How to reproduce 1. Navigate to a TAPD project, creating some iterations and issues for testing usage. 2. Update the iteration field ofissues, including some empty value for "from_value" or "to_value" 3. Setup devlake to collect the TAPD project we prepared. 4. Check from_value (original_from_value) and to_value (original_to_value) in `issue_changelogs` domain entity. You will find some value like `tapd:TapdIteration:2:0` rather than expected empty value. ### Anything else   ### Version v0.16.0 ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
