[PATCH] client: Fix missing Connected Network display

[Tim Kourt <tim.a.kourt@linux.intel.com>]

[-- Attachment #1: Type: text/plain, Size: 2241 bytes --]

The connected network wasn’t displayed correctly within Station
object when connection was created before the start of iwctl
due to object dependency and timing of the sequential parsing of
the Object Manager’s objects. The issue is corrected by storing
the network path and doing lookups of the network proxy objects
at the time of display.
