Description:
After the boot 3 / batch 5 changes you can't clean up task executions in manage / tools anymore.

Release versions:
2.11.0-SNAPSHOT

Custom apps:

Steps to reproduce:

• Create some task executions
• Go to manage / tools and clean the task executions - the information is printed that they are removed, but they aren't. 😄

Screenshots:
Where applicable, add screenshots to help explain your problem.

Additional context:
The method findTaskExecutionsByName is used with an empty task name and is going to delete nothing.
