EnforcedStyleAlignWith: start_of_line behaves strangely

[gerrywastaken]

See the third good example under the start_of_line section in the docs:
https://www.rubydoc.info/gems/rubocop/RuboCop/Cop/Layout/EndAlignment

Copied here for posterity:

variable =
  if true
  end

---

Expected behavior

This passes

variable =
  if true
    :foo
  else
    :bar
  end

Actual behavior

It errors with:

bleh.rb:5:1: C: Layout/IndentationWidth: Use 2 (not 4) spaces for indentation.
    :foo
^^^^
bleh.rb:6:3: C: Layout/ElseAlignment: Align else with variable.
  else
  ^^^^

but this passes:

variable =
  if true
  :foo
else
  :bar
  end

Steps to reproduce the problem

with the following in your config:

Layout/EndAlignment:
  EnforcedStyleAlignWith: start_of_line

run rubocop on a file containing this:

variable =
  if true
    :foo
  else
    :bar
  end

RuboCop version

$ [bundle exec] bundle exec rubocop -V

I have tested the fix yet, but I just wanted to say thanks for working on it. :)
