The plot should be invariant against reordering of the table rows

As it can be observed when running this code: #175 (comment)

Shuffling the rows of the table changes the plots, while it should not. This happens because currently instance_key is ignored. A solution is to call the function match_table_to_element() to match the rows of the table to the geometries to display https://github.com/scverse/spatialdata/blob/bf3377fd36f94ef51a233ae71312b1c28e978e6e/src/spatialdata/_core/query/relational_query.py#L134.

Weirdly, the bug appears only for labels and not for circles. The reason is probably the use of the fragile mechanism around _labels_key in _model.py, reason for which I suggest to first clean up the codebase around the model as described here #180, and then address the current issue.

Based on #208 I will close this.
