Updated git submodules

Project: appc master 57c37a4a6f390ed059897d5b382a59d1e1443852

Rename file due to case conflict on windows

Both Start.json and start.json exist in appc-sequence-generator-bundle/src/test/resources/output.
This causes issues when working in a windows environment as both files cannot exist.
Renamed Start.json to Start2.json and updated the test accordingly.
