fix(test): update teardownSourcePacket callers for the new signature

Threading the reset sequence through teardownSourcePacket changed its
signature and left the three C1 test call sites on the old one, so the
package failed to build. A local compile would have caught this instantly;
with no Go toolchain here, CI is the first compiler this code meets, so
signature changes need every caller checked by hand before pushing.
