fix: lock owner in file details

[kulmann]

Description

We were showing () for for the Locked by field in the file details for two reasons:

1. the lock owner propfind info was referencing the wrong field name
2. the () were shown if there was no lock time

Fixing this by

1. Referencing the correct field (after the backend prettified the string in that field)
2. Showing (<lockTime>) only if there is a lockTime and hiding the parentheses entirely if there is no lockTime info
