Support Oracle driver 4.0.0

[kibertoad]

Currently tests are failing when latest Oracle driver is used.

I should take a look what causes it. Previously there has been bugs in new versions of oracle drivers.

Maybe we should write down the errors which are happening? That would help to find this issue.

I have now the following one popping up: Error: ORA-12519: TNS:no appropriate service handler found. That seems to create a timeout my Ava test can not handle properly.

Edit: This error was occurring due to an internal Oracle ATP 18c bug.
I am actually using the driver version 4.0.1 of oracledb with latest knex 0.19.4 and I cannot complain about problems. But likely that I do not use all the functionality.

@PeterMerkert Are you using blob functionality? I think that's the part that is failing.

[PeterMerkert]

@kibertoad Nope, I am not using any blob functionality. I use select, several joins join, update, delete and raw statements.

Was this fixed by #3480 ?

[kibertoad]

Should have been, yes.
@PeterMerkert Could you please try using 0.20.0 and report back?

[PeterMerkert]

I got the upgrade and for me all my features are still working. The new version is in my code.

But remember, I have reported before that I did maybe not use the functionality which was broken in the first place.

Thanks a lot for the new version though anyways!

@PeterMerkert Awesome, I was wondering if we broke something while fixing something :D
