Remove unknown parameters in patched update

When updating a stack with the existing flag, we keep the parameters
from the old template to be used against the new version. Sometimes
parameters will get remove and won't make sense anymore, and keeping
them would break update with a 'Parameter was not defined' error. This
filters out such parameters so that the updates succeed.
