Reset feature flags before assertion

[mrmr1993]

This PR changes the handling of feature_flags in Pickles for wrap circuits. Previously, we were propagating the flags from the step circuit, which could cause a sanity-check assertion to fail when we convert the 'full' set of values back to the 'wrap only' set of values. This PR fixes that by always resetting the flags before entering that conversion.

This PR does not change any circuits, protocol constants, etc.; the behavior is only changed when those offending flags are set. As such, this can be deployed to snark workers as a compatible bugfix version.

Tests to follow.

Merging through versioned-type-linter; it's broken whenever the tip of rampup is a PR that didn't change the daemon code :(
