Workflow condition "Any Change" doesn't work on integer fields

[BastianHammer]

When building a workflow, that is checking for "Any Change" of an Integer field, it seems to be always true.
Even though there is no change or no value inside the integer field.

Building the same workflow logic on a text field or decimal field, things work as expected.

Issue

Expected Behavior

If there is no change / no value inside the integer field, the condition should validate false and the workflow should not be triggered.

Actual Behavior

No change, still validates as true and the workflow is being triggered.

Possible Fix

Steps to Reproduce

1. Add an integer field
2. Add a workflow that triggers on change
3. Change (or just edit and save a record without any changes)
