Problem using TRestRun to open a fresh generated file while processing data

[jgalan]

This problem appeared at rest-for-physics/axionlib#12

I suspect the problem is related to the intermediate encapsulation added by TRestAxionEventProcess::TRestEventProcess added so that we can add a common feature to any axion event process, this approach might be handy at other libraries.

When I open the file using TFile directly, I am able to access the information registered. No problem there.

The problem appears when using TRestRun *r = new TRestRun("file.root") or restRoot file.root

 *** Break *** segmentation violation

I will keep investigating but any help is welcome. @nkx @rest-for-physics/core_dev

Finally the problem was at unitialized TRandom pointer. Fixed at rest-for-physics/axionlib@a8c7ec1
