[BUG] Incorrect DB credentials gives cryptic error

[aaronsaray]

Describe the bug
Purposely, I set the password to my database connection to an incorrect value. Then I get an error of Oops... No valid database connection with a suggestion of You're using an irregular port number, usually the port is 3306 (Yours is: NaN)

Couple things wrong here:

• because of the invalid connection, the code is zero'ing out all my config - I think it shouldn't set all the values to null
• because of above, the JSON turns my port number to null (even though it's actually set right) Even so, it shouldn't say NaN - it should be filtered to parse the integer properly or display a better message

To Reproduce
Steps to reproduce the behavior:

1. modify .env DB_PASSWORD value to be wrong.

Expected behavior
I think it could tell me what the error message was, and then also not null out my values. I'd like to see them because maybe I have a typo.

Additional context
Why would this happen you ask? Well, right now, it'd be very unlikely. But, you're publishing DB credential configuration in config/prequel.php - which means you most likely want us to use them, too. My .env file could be right, so my application works, but this configuration file (when implemented) might have a typo in it.

Because this is such a particularly weird issue to have, I'd rate it as pretty low priority.

Hey, I could not replicate your issue. I having an invalid password (and username, database etc.) but it just shows me that Prequel could not find a valid connection. Something I'm missing here?

I think this was fixed in f1ab336!

Confirmed to be fixed, so closing now.
