Title: Only require MiniTest in the console if it exists.

Apparently some Linux distributions rip out rubies that are in the
standard library, like MiniTest. This causes Rails is not currently installed on this system. To get the latest version, simply type:

$ sudo gem install rails

You can then rerun your "rails" command. to fail
in production when people use Fedora on their servers.

Fixes #6907.
