fix(app): fix WellSelection over-render

[mjhuff]

Overview

Fixes a rendering issue with WellSelection, in which allSelectedWells for multi-channel pipettes is computed by passing each key of selectedTipLocations into getWellSetForMultichannel. Although some of the internal logic for that util has changed recently, it's always been true that getWellSetForMultichannel returns all the relevant wells given just one well, so we don't need to iterate over all selectedPrimaryWells with a reduce.

This over-render isn't an obvious problem until we introduced partial tip configs. Note this PR doesn't contain partial tip support, but we'll have to be more intentional about specifying just the well of interest when we do support partial tip configs (in the very very near future).

Before

8-channel with 3 active nozzles. E1 is the active well and the selectedPrimaryWells are C12-E12.

After

Same config as in the before image.

Test Plan and Hands on Testing

• See images.
• Verified this doesn't break the QT Source/Dest well component.

Risk assessment

low

Ah, nice change!

Apologies for the quick merge. Need this for the very very near future partial tip PR.
