get_sim() returns incomplete Plant entries when usms_file is provided

[sbuis]

Description

When using get_sim() with a usms_file argument, the returned simulation object does not contain the expected crop information in the Plant component.

Reproducible example

workspace_v10.zip

sim <- SticsRFiles::get_sim(
  workspace = workspace,
  usms_file = file.path(workspace, "usms.xml"),
  usm = "ICS_Bergamo-Aviron_IC_2021-2022"
)

sim$`ICS_Bergamo-Aviron_IC_2021-2022`$Plant

Observed behavior

sim$ICS_Bergamo-Aviron_IC_2021-2022$Plant contains only "ble".

Expected behavior

The Plant element should reflect the actual crop simulated in the USM and therefore contain "ble" or "poi" depending on the crop.

Additional information

• The issue appears only when usms_file is explicitly provided.
• The workspace contains multiple USMs (it's working when there is only one USM ...)
