Initial activity now checks keys before inserting into database, prevents sqlite errors at launch and enables future feature of restarting mid test
Completion activity now correctly writes responses to output file before FTPPutService runs
Removed Main activity. Now getting advertising ID in initial activity while already waiting on database to build. This is intended to push all loading / waiting into one spot and avoid it at future launches.
A bit of debugging done for writing file in 'complete' activity and reading file in FTPPutService
Slight refactoring of FTPGet task to loosen coupling with Initial activity.
