[1.7.4]Demonologist does not unlock all tinker slots, softlocks EoR

[InC]

Demonologists do not unlock tinker slots when learning tinker trees, leaving them unable to use tinkers other than on the weapon slots they get from Demonic Pact. In EoR, it leads to them getting the tinker version of the stralite sand shredder while being unable to equip it, preventing progression.
