Description
Describe the bug
Moving a readonly file throws (correctly) an UnauthorizedAccessException, but afterwards both the source file and also the target file exist.
To Reproduce
Consider the following unit test (using Xunit and FluentAssertions):
    [Fact]
    public void MoveFile_WithReadOnlyAttribute_ShouldThrowExceptionAndNotMoveFile()
    {
      var sut = new MockFileSystem();
      sut.File.WriteAllText("foo.txt", "xyz");
      sut.File.SetAttributes("foo.txt", FileAttributes.ReadOnly);
      
      var exception = Record.Exception(() =>
      {
        sut.File.Move("foo.txt", "bar.txt");
      });
      exception.Should().BeAssignableTo<UnauthorizedAccessException>();
      sut.File.Exists("foo.txt").Should().BeTrue();
      sut.File.Exists("bar.txt").Should().BeFalse();
    }This test fails at the last line, as the file exists now twice, resulting in an inconsistent state of the MockFileSystem
Expected behavior
The unit test should be successful.
Additional context
This issue might have similar root cause as #849 ?
