Accent colour changed from default to yellow

SUMMARY
When the accent colour changes, and a preview is requested again, a cached version of the first preview generated is returned.

This is problematic if the accent colour is changed.

This affects Dolphin (which presumably is making a request for the preview again after accent colour change) and WIP work for Koko.

STEPS TO REPRODUCE
1. Request a preview of a folder containing images from KIO
2. Change accent colour
3. Request the same preview again

OBSERVED RESULT
A preview is returned featuring the original accent colour (cached).

EXPECTED RESULT
A preview with the new accent colour (invalidating existing cache).
