Fix HLT-L1T seed index to be from begin BxVector

[rekovic]

ObjectMap of L1T objects is providing indices relative to Bx = 0.
This is a fix to use object indexing relative to begin of BxVector when making TriggerObjectRefs in the HLT-L1T interface module.

The fix should solve the problem of low rates of EG HLT paths observed in last night's data taking.
Please merge and make a patch for immediate data taking.

hi @rekovic , shouldn't the references for the energy sums be fixed in a similar way ?

[rekovic]

@fwyzard Refs to energy sums do not need fixes as they were already taken from Bx = 0.

I'll start a build in parallel with these tests...
