Fix failing integration tests
This fixes the app_exception_handling, continuous_sewing_hasher, and discontinuous_sewing_hasher integration tests:
- app_exception_handling is fixed by adding try/catch blocks in the gaussian_chain_test and ModelTrimmer pilot apps. Please don't add a pilot app to pilot_apps.src.settings.all unless you have its functionality enclosed in a try/catch block.
- The sewing_hasher integration tests are fixed by removing datestamps from sewing_hasher.cc. If you write an integration test, don't have it write out the date on which it was run. This WILL cause a daily failure.
