FINERACT-857: Fixing scheduler integration tests and migrating to executeAndAwaitJob

[ptuomola]

Description

Fixed two bugs that were triggered by scheduler integration tests:

• Invalid query in SavingsAccountCharge (missing parameters)
• Lazy loading not working for m_savings_account.group_id due to transaction boundary

Also changed triggering of jobs to use executeAndAwaitJob() and fixed logging for exceptions jobs

OK - looks like turning off lazy loading for group means that we have more than 61 (!) tables in a join in RecurringDeposit, which then breaks... so need to find a way to get the lazy loading to work after all...

Cool!! You are amazing. Some minor feedback..

PS: I'll search in JIRA for the open real bugs you have also fixed here.

LGTM! Would love to merge this ASAP.

@ptuomola if you are on and want to do this ASAP, it may avoid new conflicts for #943 which I'd like to do in the coming hours. If I don't hear from you, perhaps I'll even exceptionally resolve the conflict myself just to be able to merge this sooner rather then later - I'm sure you wouldn't mind.

Actually the merge conflict here was due to #1020 and trivial to resolve - I have, for once, just used GitHub's Web UI ... if I didn't screw it up, hopefully this will pass the build and I'll merge it.
