[CS] Remove outdated assertion

We used to apply builder transforms to regular
functions without using a constraint system,
which is what the assertion is primarily geared
towards. However we now use a constraint system
for such cases, with the lack of a constraint
system only being used to check if we can even
apply the transform in the first place.
