WithAutoConversion throw ArgumentException for different enums

[jnyrup]

Description

With #2147 we now try to convert the subject into an enum if the expectation is an enum.
This does not work when the subject is of another enum type.

Reproduction Steps

[Fact]
public void Test()
{
    var subject = new { EnumA.Value };
    var expected = new { EnumB.Value };
    subject.Should().BeEquivalentTo(expected, o => o.WithAutoConversion());
}

enum EnumA { Value }

enum EnumB { Value }

Expected behavior

Test should pass

Actual behavior

Message: 
System.ArgumentException : Object must be the same type as the enum. The type passed in was 'TestProject19.UnitTest1+EnumA'; the enum type was 'TestProject19.UnitTest1+EnumB'.
