Fixes order of logging metrics and sampling commands in command manager (#1352)

# Description

In the command manager, we were logging the metrics after resampling the
commands. This leads to incorrect logging of metrics when inside the
`resample` call, the metrics tensors get reset. This MR fixes the order
to make sure the bug doesn't happen.
