Selene mistakes variables as being 'shadowed' in some situations with anonymous functions in events

[NobleDraconian]

Currently (with selene 0.6.0), selene will mistake an event parameter as being 'shadowed' if an anonymous function is used in an event connection, and a previous event connection uses the same variable name. I was unfortunately not able to get a solid reproduction when I tried reproducing the issue.

Actual problem: if there is an empty else block, it causes problem with the shadowing lint. Easy repro:

local foo = function(bar)
    if bar then
        print(bar)
    else
        -- This causes problems
    end
end

local baz = function(bar)
    print(bar)
end
