fix(app): Tolerate old tip length calibration records without a uri field

[SyntaxColoring]

Overview

This fixes RESC-215.

Apparently, old tip length calibration records don't have a uri field. (It looks like uri was introduced in #7136, v4.1.0.) We used to safely drop these records via this except ValidationError block. But PR #14512 started accessing the uri field manually, accidentally bringing it outside the coverage of the except block and turning it into an HTTP 500 error.

Test Plan

To reproduce this manually, you can download the data/ directory from RESC-215 and run this in the api project directory:

OT_API_TIP_LENGTH_CALIBRATION_DIR=/path/to/downloaded/data/tip_lengths \
  pipenv run python -c \
  'from opentrons import calibration_storage; print(calibration_storage.get_all_tip_length_calibrations())'

On v7.1.1, it will work. On v7.2.0, it will raise an error. On this branch, it will work again.

I've also added a unit test.

Changelog

• If uri is missing from an old tip length calibration record, silently ignore that record.
• Fix a misplaced JSONDecodeError catch. (This turned out to not be the problem, but it's still probably a good idea to fix.)
• Add exception info to a bunch of parsing warnings to make these problems easier to debug. (These warnings turned out to not cover this problem, but it's still probably a good idea to fix.)

Review requests

• Is there a better way to handle these records than skipping over them entirely?

Risk assessment

Low.

Nice debugging and fixing max :) I also don't know when we added in URI because I thought we've had that component for a long time. Maybe I only added it in when doing calibration stuff for the flex, but it's been a while so I can't remember.
