🐞 Example product has correct property names

Properties were inadvertently named `foo_2_0-committed` instead of `foo_2_0`,
which caused the tile upgrade to fail during credhub JS migrations.

fixes:
```
Could not apply migrations. '201705060201_example_credhub_credential_migration2_1.js' has javascript errors 'This tile contains an invalid migration: One of the objects in the variable_migrations array has an invalid structure.
```
