Fixed awkward checkout text in checkedout side panel

[akemidx]

Description

When checking out an asset, and no asset assigned to the user selected, the page was trying to add the user's name into a line stating no assets assigned for that user. This was bugged and this PR removes that bit of code to make the line read correctly.

Fixes SC-19909

[what-the-diff]

• The first diff changes the text of a table header from "Current Assets" to "Assets Assigned".
