[FIX] iap: fixing display in the crash manager

Before this commit, there was a default behaviour reducing the padding of the qweb render
to 0 in order to display bakcground images correctly. Unfortunately, this doesn"t take in account
cases where images or more generally, qweb template were not provided in the InsufficientCreditError
message.

This commit solves this situation.
