TrigHLTJetHypo+TriggerMenuMT: use exception for empty HypoTool
Throw a NoHypoToolCreated
exception in case no HypoTool was created in
the generator function. Returning None
as in the previous code results
in duplicate empty tool names in the ToolHandleArray (ATR-23920).
In addition remove the redundant copy of tool names and getTools
accessors in
MenuSequence
(the ToolHandleArrary
already ensures we are not adding
any duplicates).
Also remove a few explicitly set log-levels in various places.
