Results detected from ScanCode should be pre-populated in the conclusion pop-up

[JonoYang]

When I open a conclusion pop-up, the detected ScanCode values should be pre-populated if I did not save a conclusion before

• if there is only one value it should be picked
• if there are more than one value, they should be aggregated as a license expression or composite copyright or the main one should be picked
  • a component name should be suggested

This goes alongside #270

IMHO we should reconsider the conclusions features to use instead ScanCode.io for a more comprehensive approach.

Closing because we are deprecating the Conclusions feature in favor of building it into SCIO.
