The test coverage for sjrk.storyTelling.blockUi.editor.imageBlockEditor is incomplete. Add a few more tests:

• check the grade names to ensure the fluid.contextAware merging is happening as expected (no longer applicable)

• call the updateImagePreview invoker manually and check the resulting values

• on imageUploadRequested, check that singleFileUploader's onUploadRequested also fires

• on imageCaptureRequested, check that cameraCaptureUploader's onUploadRequested also fires (no longer applicable)

• check that updateImagePreview is called with the correct arguments when singleFileUploader's fileObjectURL changes

• check that updateImagePreview is called with the correct arguments when cameraCaptureUploader's fileObjectURL changes (no longer applicable)

Also consider these possible additions:

• check the template has been rendered as expected

• check the bindings
