Romain Derie 755ab30619 [FIX] website: prevent traceback when iframe has no src
Commit [1] introduced an cleaning of the iframefallback on page unload,
which was removing the `autoplay` attribute of the iframe `src` URL.
It was done to prevent video/music to keep playing in the invisible
iframe.
The fix was not generic and purposely targetted the elements which we
identified as problematic.

Commit [2] then made that cleaning generic, catching all iframe.
Doing so, it was actually catching too many iframes and led to traceback
on iframe not having a set `src`.
This is the case for every database having a configured reCaptcha, among
other things.
For reCaptcha, it's because it's adding the following iframe dynamically
through their third party script:
`<iframe style="display: none;"></iframe>`

This commit ensures we only target iframe having an URL attribute being
set to something.

Step to reproduce (with reCaptcha):
- Enable and configure reCaptcha
- Go to /contactus
- Leave the iframe page, eg click on "Contactus" menu to refresh it
-> Traceback
