As a query builder I want to be able to remove the remaining query in order to quickly start over
Problem:
Currently, when only one condition is remaining, the delete button gets disabled which is inconsistent with the previous behavior. This can be confusing and also a hindrance when trying to remove a prior query.
Example:
BDD
GIVEN a visual query with only one condition
WHEN clicking the trash can icon
THEN the condition is removed
AND the space of the condition is replaced with a place holder text
Acceptance criteria:
- remove the disabled state of the trashcan (last condition can be deleted as well)
- when no condition remains, a placeholder text becomes visible (see figma specs)
