Respect "Starting Position" in task when using an Annotation ID as Base

[philippotto]

Context

Tasks with a base annotation will always use the edit position from that base annotation instead of the one which is provided when creating a task.

Steps to Reproduce the bug

• Cannot reproduce the bug anymore / needs deeper investigation.

1. Create a new task type with volume enabled
2. Create an annotation, go to position 100, 100, 100, save and copy its id
3. Create a new task, select the task type from (1) and select "Use Annotation ID as Base" where the id from (2) should be pasted in
4. Enter a Starting Position (e.g., 1, 2, 3)
5. Go to dashboard, get a new task and open it
6. The active position should be the one from (4). Instead, it is 100, 100, 100.

Your Environment for bug

• Browser name and version: e.g. Chrome 39
• Operating System and version: e.g. Windows 10
• Version of WebKnossos (Release or Commit):
• Specific to long-running jobs (set jobsEnabled=true in application.conf)
• Specific to webKnossos.org (set isDemoInstance=true in application.conf)

Should the same go for bounding box and edit rotation? I’d guess so, right?

[philippotto]

For the edit rotation, yes, I'd say so. For the bounding box, we usually differentiate between the task bounding box and dataset/annotation bounding box. I didn't check what the current behavior with an annotation base is, but it should probably use the bounding box from the task form as the task bounding box.
