Dockerfile-per-task not working with map_tasks

[jvfe]

Describe the bug
I'm unable to use the dockerfile-per-task feature if the task with the specific Dockerfile is being used inside of a map_task.
I currently have a test workflow showing this bug, one version uses map_tasks while the other uses a simple task. In
both cases, the workflow registers without issues, but, when running the one with a map_task, it fails on the second task, giving me an error saying that the software - which should've been included in the dockerfile - cannot be found. The one with a simple task runs without issues.

I'd guess this is happening due to some issue with how map_task and task-specific dockerfiles interact because the first task in the workflow, which doesn't require any external dependencies, runs without issues in both versions.

To Reproduce
Steps to reproduce the behavior:

1. Go to the workflow version that currently doesn't work
2. Start running the workflow with the default test data
3. The first task will execute without issues
4. The second task, a map_task (mapper_taxonomy_classification_task_0), should fail.

Expected behavior
I expect to be able to use dockerfile-per-task with map_tasks.
