Updated attribute not being flagged as dirty

[FrancisMawn]

Describe the bug
Let's say we have a User model with a "code" attribute.
Updating $user->code from '001' to '01' will not get logged when using the logOnlyDirty() method.
NOTE: This is not a configuration issue as everything else works as expected.

To Reproduce

• Configure a model to only log dirty attributes

return LogOptions::defaults()
            ->logOnlyDirty()
            ->dontSubmitEmptyLogs();

• Set a string attribute with digits (i.e. "123456")
• Update the attribute to add leading zero(s) (i.e. "0123456")
• No activity logs are created

Expected behavior
Since the model attribute has changed, I would expect an activity log to be created.
