debug stuff in ncer production

@piotr.gawron as mentioned in the mail.

The settings.py had ‘debug_toolbar’ in the INSTALLED_APPS and then migrate didn’t work properly. I had to comment it but still it didn’t work properly so I opted for installing the debug requirements. I understand this is a debug requirement and we should fix it. Because of this, the availability of the prc production served was compromised for about 1 minute until I fix it.

What should we do about it?
