Summary0033767: Add code to auto-detect 'accidental double query' on same OBQuery or OBCriteria object
DescriptionThere is a quite common bad coding pattern which calls '.list()' more than one time on the same OBCriteria or OBQuery object.

That will call the underlying sql query also 2 times.

Similar some code without good reason calls .count() + then .list() on the same instance. Which leads to a 'select count(*)' + then another 'select *' sql query.

Detecting such pattern is easy with some extra debugging code inside those 2 utility classes.

See attached patch for a rough patch doing some simple tracking.

Not polished yet but did already find 6 issues in fast manual testing + more 'to be triaged' when running erp-try with it applied.

The attached patch logs a WARN + a stacktrace of the location of and 2nd or 3rd call to either list,count,scroll.uniqueResult.

In practice that 2nd location is enough as a pointer and finding the first call in code is very easy in all examples observed so far.

Accidental double query in OBCriteria is now detected with the fix for issue 0033816. It will be detected because the initialized method of the OBCriteria instance will be invoked twice, and in that case a warning is displayed in the log.
