Data path is hard-coded to 'ring' on macOS and Windows
Commit 08df7d47 hard-codes the data path as QStandardPaths::GenericDataLocation + 'ring/' which yields:
- %appdata%/ring on Windows
- ~/Library/Application Support/ring on macOS
This is a temporary hack to retain the data location during the Jami re-branding process.
These paths should use QStandardPaths::DataLocation which uses the name of the application.
