Project archive with incomplete execution causes error on import

[gschueler]

If a project archive was created while an execution was running, then imported, it will cause the following error:

ERROR GrailsExceptionResolver: Exception occurred when processing request: [POST] /project/importArchive
Stacktrace follows:

Workaround is to unpack the archive, find the execution.xml which has an empty dateCompleted tag, and change it to a valid date. Repack the archive and upload.
