pystac_client.Client.open().get_collection() always returns last collection

[FlorisCalkoen]

When you connect to the catalog using pystac_client and use get_collection() to retrieve the collection of interest, you always get the last collection. However, when you do catalog.get_child() it works as expected. See below.

import pystac_client

coclico_stac_href = "https://coclico.blob.core.windows.net/stac/v1/catalog.json"
catalog = pystac_client.Client.open(coclico_stac_href)
catalog.get_collection("gcts-2000m")  # returns the last collection...? at time of writing the shorelinemonitor sample

catalog.get_child("gcts-2000m")  # works fine

Not sure if we have a bug while building the STAC, or that our stac is not compatible with pystac_client or that its a bug with pystac_client.
