Description

If a variable name is changed in the main workspace, the minimap will still show the old name.

Reproduction steps

1. Open the minimap test page here https://raspberrypifoundation.github.io/blockly-samples/plugins/workspace-minimap/test/index.html
2. Create a new variable, name it "a" and drag a "set a to" block it into the main workspace.
3. Click on the variable name in the block, and "Rename variable...", changing it to "b".
4. The block in the minimap will continue to show the name "a".
