Fixed various Dropbox issues + unit tests
- fixed touch function to return true on success - fixed local metadata cache to remove deleted files/directories - fixed getMetaData() to ignore files reported as deleted by Dropbox - fixed "file not found" case to not log as exception - fixed "overwrite on rename" case - fixed unit tests to exclude unsupported cases - added unit test for touch return value - unit tests for Dropbox should all run correctly now
