before this commit, on reading data with default dict data
type is showing error to end user, without returning the
requested data.
for eg, if a read operation is triggered on model sale.order
it wont return the requested data, instead traceback is
shown in response.
in sale.order model the tax_totals field is a computed
field, with data as format default dict which was
causing the issue.
after this commit, without any traceback the requested
data will be returned to the user.
