Space on the end of a database connection URL during setup can cause connection to fail.

When performing the "Setup Standard Database" step in Confluence setup, I accidentally had a space on the end of my Database connection URL:

jdbc:mysql://localhost:3306/confluence?autoReconnect=true&useUnicode=true&useServerPrepStmts=false&characterEncoding=UTF-8

The space caused the MySQL connection to fail because it was looking for a character set called "UTF-8 " instead of "UTF-8"

Neat, huh?
