Typo in FJR attribute name
**Impact of the bug**
WMAgent/CRAB

**Describe the bug**
As mentioned on this commit:
https://github.com/dmwm/CRABServer/commit/a647fa3eb5d728d53f502646bdfc2d582b2abe8e

WMCore is setting, there is a typo in WMCore where the file attr `output_module_class` is set as `ouput_module_class`

**How to reproduce it**
None

**Expected behavior**
We should rename the attribute to `output_module_class`, here:
https://github.com/dmwm/WMCore/blob/master/src/python/WMCore/FwkJobReport/XMLParser.py#L96

and fix whatever unit tests need to be fixed.

**Additional context and error message**
none
