Whoops reporting "loaded already" modules

[ghost]

Discussed with @mahagr

There have been several instances where whoops is reporting that PHP modules have been loaded already. This seems to have changed recently. Although this is highly likely to be a php configuration issue it is unfortunate that Gantry 5 (specifically whoops) is spotting these and therefore Gantry 5 breaks (forever spinner, or whoops message).

It would be good if we can just log these errors and carry on and have Gantry 5 not break under these situations.

I did not mean to close this issue. Not sure if the above fix works as I'm unable to reproduce the issue.
