Subject: [PATCH] fix(interaction-failure): clear interactions on any verify()

All successful/failed calls to pact.verify() should clear
interactions so that subsequent tests don't det out of whack.

NOTE: Promise.finally() would have been nicer, note for
upgrade to latest TS in next major release.

Fixes #231
