fix: lsmeas use name instead of channel label

When a element is renamed using renameelem the macro
lsmeas still shows the previous name (label) sardana-org#1053.

We propose to adquire and show the name of the
elements of the measurement group from the full name
(i.e: ct1, ct2, sys/tg_test/1/ampli).

closes sardana-org#1053.
