Variable name bug

[thsparks]

Describe the bug
Variable names seem to be getting replaced with "blockly-#" in certain scenarios (local builds only at the moment).

To Reproduce
Steps to reproduce the behavior:

1. Build and run localhost (bug is not in live)
2. Create a variable and drag in a "set" block for it
3. Right click and look at the "create getter" option in the menu
4. Expect: Create 'get myVar'
5. Actual: Create 'get blockly-1'

I saw this happen once while undo-ing changes, it changed the block itself to say blockly-1, but not sure on exact repro for that.
