#1712 fix patching a thing, removing items did not correctly upgrade …

…the thing on the UI

* fixed by solving the merge on Ditto server side, selecting all "extraFields" for each change .. that way, the complete updated thing is emitted via the SSE instead only the diff
* as a result, also deleted the "merge" functionality of the UI, also removed no-longer needed "lodash" dependency
