tec: Improve logs on DB connection failure (#2734)

For a moment, PHP wasn't able to connect to my database. I tried to
understand what happened, unfortunately, the logs were not very helpful
(it basically showed me information that I had in my configuration
file).

I changed the dsn string by the message from the raised exception, I
think it will be more useful.

Other call of Minz_PDOConnectionException are passing error messages
instead of string connection, so I took the opportunity to rename the
constructor argument.
