improvements for creating and editing properties, removal of aliases

[frog23]

this combines three commits which increase capabilities of quickstatements:

• the labels, descriptions and aliases of properties can be edited
• aliases in general can be removed
• properties can be created (this is not so much relevant for wikidata.org, but for independent wikibase installations)

Hello!

I can confirm that this fixes issues with label, description and properties for the wikibase-docker images.

I've spent most of today writing tests for quickstatements that is included in the wikibase bundle and have a pull request up here with the newly added tests.

I've we compare this is a run on master of this repository https://github.com/wmde/wikibase-release-pipeline/runs/2411450022?check_suite_focus=true

However I haven't tested the additional functionality, maybe the fix and the added feature should go in separate pull-requests?
