PHP Fatal error: Cannot instantiate abstract class Installer in .../includes/installer/Installer.php on line 468, referer: http

I'm looking at this, and I believe I know what is causing this.

Steps to reproduce:

  1. Disable the PHP mysql extension (leaving PDO SQLite enabled).
  2. Restart Apache/PHP.
  3. Choose "Restart installation" in the MediaWiki installer (if necessary).
  4. Follow instructions until arriving at the "Connect to database" page.
  5. Click "Continue". Do not select SQLite or any other DB type.

Patch in Gerrit awaiting review, might be nice to get this in for 1.21.0.

Definitely need this in 1.21 -- I found it when a client was working on their 1.21 upgrade. I would prefer that Chad reviews it, but since he seems to be busy, I will.

Tested and confirmed the fix works. Merging into 1.21
