[kacieje]

Description

This PR removes an unused coffee component summary-task-status-scatter. No references to this visualisation could be found for initialisation and it could not be triggered in testing.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

Triggering of the component was tested by searching through the code base for references to the component (summary-task-status-scatter and summaryTaskStatusScatter). The component itself (summary-task-status-scatter.coffee) and the visualations template (visualisation.tpl.html were located but no triggers for actual use. Once the changes in this PR were applied, various visualisations were tested and no changes to their functionality were identified.
