`esc` unaligns the cursors, when real cursor on first column

[duianto]

esc unaligns the cursors when the real cursor is on the first column, but at least one fake cursor is not.

Reproduction steps

With multiple words in a buffer.
and at least one word is indented.

abc
  abc
    abc

• In evil normal state, create evil-mc cursors on all occurrences by pressing: grm
  The cursors appear at the end of the words.

ab[c]
  ab[c]
    ab[c]

• Move back the cursors to the beginning of the words: b

[a]bc
  [a]bc
    [a]bc

• Enter evil insert state: i

|abc
  |abc
    |abc

• Exit to evil normal state: esc

Observed

The fake cursors moved to the left once.
They are now unaligned with the real cursor.

[a]bc
 [ ]abc
   [ ]abc

Expected

The cursors should remain aligned.

[a]bc
  [a]bc
    [a]bc

This might not have an easy/desired fix.

The default behavior in Vim when exiting (esc) from insert state to normal state, is that the cursor moves back.
This causes the evil-mc cursors to become unaligned, when the real or a fake cursor is at the beginning of a line.

[a]bc
  |abc
    [a]bc

esc moves back the cursors that are not at the beginning of their lines

[a]bc
 [ ]abc
   [ ]abc
