Site not respecting the usepdfexport flag

[Robert Lyon]

With the new pdfexport option there are a few things that need to be true before it is used.

1) The chrome-php plugin needs to exist
2) The $cfg->usepdfexport setting needs to be true
3) The active setting in export_installed table needs to be true

However, it will still do the export if point 1 and 3 are true - ignoring the usepdfexport flag - if installing a new site (not upgrading)

To test (before patch):

1) checkout master
2) run make pdfexport - and also make sure any other pdfexport dependencies are met eg pdfunite
3) set config.php with: $cfg->usepdfexport = false;
3) install site
4) do an export and see pdf being built in it

So we neeed to adjust the code so that all three things are respected
