refactor(protocol-designer): figure out why getTiprackVolume() is failing

[ddcc4]

Overview

Adding instrumentation to figure out why failures like this are happening:
https://opentrons-76.sentry.io/issues/6841220504?project=4509363266387968

We're calling getTiprackVolume() with a tip rack definition of undefined. That could happen because:

• The tipRackDefUri (which comes from the form) is undefined.
• Or it is defined, but we can't find it in the pipetteEntity.tiprackLabwareDef array.
• Or pipetteEntity.tiprackLabwareDef is empty for some reason (the original code tried to use pipetteEntity.tiprackLabwareDef[0] as a fallback, which I don't think helps anything).

This PR simplifies the code and adds more information to the console.assert() to help us figure out what's going on.
