Fix initial job priority at job submission
**Impact of the bug**
Job priority of jobs at submission time are wrong. This affects the priority of job types, setting them to values that are too small until they get edited in the condor pool, once a new request priority takes place.

**Describe the bug**
Job priority at submission time is not taking into account the `maxTaskPriority`.

UPDATE: This issue has been introduced with this PR: https://github.com/dmwm/WMCore/pull/9133

**How to reproduce it**
Just submit any workflow

**Expected behavior**
Job priority should be: `(priority + taskPriority * maxTaskPriority)`
where `maxTaskPriority` is a big constant number.
