FIX: do not escape special characters on user and password

[scipioa]

User and password fields are already between quotes: add the escape character '' gives wrong password or username.

Hello @scipioa , this is a long shot since you posted this pull-request a few years ago, but are you still interested in applying this change? If you do might I suggest to use strong quoting?

[scipioa]

Hi @MichielMag , Yes, this change is still relevant. I don't really see the point of using strong quoting. This commit was used in production and worked fine.

Hey Scipioa, thanks for responding! The reason I suggested strong quoting is because your fix only fixes one edge case. A problem like #81 would still happen. I think strong quoting tackles both issues.
