[FIX] Remove existing annotations from data dictionaries

[surchs]

• Closes If a user provides an annotated dictionary, the app ignores it but keeps the annotations #677

Changes proposed in this pull request:

• expandable warning button on home page to say "can't reuse"
• strip "Annotations" keys from data dictionary after loading in store
• note: there is no test for this because the processDataDictionary store method never had a test written ...
