Modified the SCTLorentzMonTool to select tracks before looking for tracks with holes in order to reduce processing time

The previous MR in the SCTLorentzMonTool made the processing very slow (this JIRA : https://its.cern.ch/jira/browse/ATLASRECTS-5572). In this MR, the track selection is done before looking for tracks with holes. Therefore the tracks with holes are used only when they satisfy the selection criteria in order to make running faster. One boolean is added in order to switch between trRunTier0Tests.logacks with and without holes.
