NullPointerException when saving new incoming commits

[KilianKrause]

Sometimes, when scanning and saving new commits, a NullPointerException is thrown in the CommitAdapter.
This can occur when the daterange of a project is set to something else than null.

Exception in thread "task-1" java.lang.NullPointerException
