Avoid creating an undefined start_phases entry when generating a release
When a release is generated and the applications in the release do not define a value for the start_phases entry of their .app files, reltool will generate the following entry in the .app files of the release: {start_phases, undefined} If this happens, when trying to create a release upgrade systools will fail because it doesn't allow the start_phases entry to be set to undefined. This patch avoids this situation by not generating a start_phases entry when it is set to undefined.
