Fix PHP Notices

[jeremylichtman]

The following patch fixes items in the module file that were causing PHP notices, which in turn prevented the AJAX callback from completing.

1. Switches to checking the project's published status, instead of the old reason_not_active field, which doesn't exist any more.
2. Moves the location where the "has_results" variable is set to true, to inside of the "if" statement that determines if there is a result.
3. Defaults the "html" variable to an empty string at the top of the function.

This looks good. A lot of these modules were developed with php notices turned off so you'll probably encounter them frequently. Once we give a test of this it'll be nice to roll it into the module.
