TESTask logs.logs.exit_code not present in some cases

[LakiG]

In some cases, the TES Task does not return the mandatory logs.logs.exit_code value. The state is different for each case, so the exact conditions cant be pinpointed to reproduce this.

The test was done on the https://csc-tesk-noauth.rahtiapp.fi/ server.
