Cleanup after functionalities/alias/TestAliases.py

This test is run after TestAbbreviations and was making runCmd("h") fail
in that test, on the second tested architecture (two commands would be
avilable for "h": "help" and "hello").

Later I'm sending a patch for review to add some information to the error
message for that case.
