Bugfixes in [role] tag

Browse Source 
The following fixes were applied:
* cfg.__shallow_literal -> helper.shallow_literal, to allow calling the tag
  from Lua as wesnoth.wml_actions.role
* added trim() to the for cycle
* deleted filter.role and filter.type after having copied their data, because
  when calling the tag from Lua they ended up being deleted too early
* unit.role = cfg.role -> unit.role = role
