Fixes#48
The `getReflectionText` method was calling `getString` when no reflection has been submitted. This is not a relevant case for the editing form since it can not be accessed when there is no reflection. Inlined the method call and removed the non-submitted case, the default will be an empty string.
## How to test
1. Log in as a supervisor
2. Open a project that has a Daisy connection (`identifier`is non-null on the `Project`)
3. Go to the "Finishing up" tab
4. Go to the tab for the author with no reflection submitted
5. See that no warning is logged
