Re: [pgAdmin4][Patch]: RM #3659 Query tool does not give warning whenAuto Commit is turned on in an incomplete transaction

The behaviour doesn't seem quite right here. I see two issues:

1) It complains that a transaction is in progress if I try to turn auto-commit on in a freshly opened Query Tool. As I haven't done anything yet, I shouldn't get the warning. I think the logic to determine whether or not we're in a transaction isn't correct.

2) In the case above, the setting is changed anyway. I think this has the potential to be confusing (and potentially dangerous); we should only allow the setting to actually be toggled when there's no transaction in progress.

Given 2), I wonder if we should remove the warning entirely, and just disable the menu options whenever a transaction is in progress.

I've attached an updated patch - I started tweaking the messages, so please base additional work from that.

Thanks.
