Replace the usage of some aliases in tempest
Replace the usage of some aliases in tempest

After [1] was merged, I found out there are still 2 places
in which the aliases haven't been replaced yet.
Therefore, I did some final checks again to make sure
all the aliases have been covered.

This patch set replaces the remaining aliases in these 2 places.
