Fix role update issue #46

[dreamsoftech]

From #46:

When role titles are camel cased, it creates new role named downcased instead of updating properly.
For example, when I have role named Community Member, it creates new role named communitymember instead of updating role by community_member.

this was supposed to turn the array into roles

Suggested change

	@user.roles = @selected_role_names.map(&:underscore)
	@user.roles = @selected_role_names.map { |r| Refinery::Authentication::Devise::Role[r.underscore] }

@bricesanchez looks okay to me; what do you think?

[parndt]

For some reason, CI is seriously unhappy with it.

[dreamsoftech]

@parndt It seems like it needs to rebase this branch against master.

Thanks for this bugfix!
I will be ok to merge it if CI goes green

[parndt]

thank you!
