fix trigger decoration name issue in AnalysisTop for name containing . and -
As explained in this jira, in the lastest release, the new event auxilliary decoration name no longer allows "." amd "-". This is relevant to trigger decorations, e.g. HLT_2j35_bmv2c1060_split_2j35_L14J15.0ETA25
So we fixed trigger decoration name issue in AnalysisTop by changing "." to "p", "-" to "_".
