Oracle function tests don't work on CI

[sebastienros]

The tests work fine on Windows and Linux but not on Helix CI. Verified on test Helix images too with the same error:

Tested without the DCP proxy too (app connecting directly to 1521 port on Docker).
Verified that the DCP proxy and the Oracle service were reachable using a TELNET connection.
Verified the password in the connection string matches the one passed in ORACLE_PWD.

Closing as a state issue.

This is Skipped in the tests right now. Instead we can quarantine it.
