ATLASRECTS-5746: "No Free Pass"

Tracks passing a selection designed to identify photon conversions were given a shortcut through the ambi for a small efficiency gain. This had the unwanted side-effect of allowing electron brem tracks (mostly in the forward direction) to have incorrect hits and overshare IBL hits lowering the EM LH identification rate.

Simple fix - remove short cut Impact on digest - 3 tracks over 3 events

Seems to fix the bulk of the differences reported in ATLASRECTS-5746
