InsertText method inserts lone carriage return characters as new lines.

[SeeminglyScience]

Steps to reproduce

1. Open a existing script file with CRLF end of line sequence.

2. Move cursor to the end of the file.

3. In the integrated console run

$chars = $psEditor.GetEditorContext().CurrentFile.GetText().ToCharArray()

$chars.ForEach{
    $psEditor.GetEditorContext().CurrentFile.InsertText($PSItem)
    Start-Sleep -Milliseconds 50
}

The file will be reproduced character by character, but with double lines.

Looks like this repros only on Windows from what I can tell so far.
