Ensure Database is set in Tracker #215

Perform an added check to ensure the database is connected prior to returning it.
Corrects an error encountered in bulk tracking with PIWIK_TRACKER_MODE set.

What error? how do you use bulk tracking and manage to trigger such error?

I am using 2.0.3 and an token_auth for bulk tracking, as well as have $GLOBALS['PIWIK_TRACKER_MODE'] set to true.

On every valid bulk request submission I had the following error,

PHP Fatal error: Call to a member function fetchAll() on a non-object in ... /piwik/core/Db.php on line 164

I found that fetchAll() retrieved it's db object from get(), which was calling Tracker::getDatabase(), which was returning null.

Upon adding my check, everything worked.

Don't set $GLOBALS['PIWIK_TRACKER_MODE'] to true and it should work

If it's not set, then my token_auth fails validation.

can you try with latest 2.0.4 beta version?

Reopening until this is resolved.

if there's a bug please, let's open a bug report first...

Thanks, it's been fixed (and integration test added, so it does not break again in the future!)
