[1.90] -Tin cable can carry more than 5 EU

I find a bug with the tin cable: if you connect one of it to a LV, MV or HV input, it will be removed.
But when you're adding energy on the cable with solar pannels: I mean when making solar plants, you can make a tin cable wich is carrying more than 5 EU/t.
In fact, there's no limit of energy for tin cable when connected with more than 5 EU but from sources of less than 5EU.
In the same way, MFSU and Tier III devices can eventually accept more than 512 EU/t (One day i make a mistake with a solar farm, and my mass fab+MFSU have received 513 EU/t without any problem.)
