Fix job_data_$expid "counter" entry

The counter entry seems to be wrong. Discovered in !531.

Expected behavior:

Having a job with the same name running 6 times.

There should be 6 job entries, each with a different counter where the values are {0,1,2,3,4,5}

What happens:

There are six job entries, but when more than one different section job is running, the value is odd per ex. {20,21,22,23,24,25}

Where is the issue:

I guess that the "counter" value in Autosubmit is not reset and is counting it per platform, so the problem is with the log retrieval function that calls the db insert
