`sol_component_value_edge` should call `_IM.sol_component_value_edge`

[matteorossini]

sol_component_value_edge should call _IM.sol_component_value_edge instead of _IM.sol_component_value:

PowerModels.jl/src/core/solution.jl

Lines 34 to 36 in 797008d

	function sol_component_value_edge(aim::AbstractPowerModel, n::Int, comp_name::Symbol, field_name_fr::Symbol, field_name_to::Symbol, comp_ids_fr, comp_ids_to, variables)
	return _IM.sol_component_value(aim, pm_it_sym, n, comp_name, field_name_fr, field_name_to, comp_ids_fr, comp_ids_to, variables)
	end

Great catch! Fix is on its way.
