ExpandoColumn is updated to database always, even if it was not modified

Steps to reproduce

1. Activate hibernate sql log adding hibernate.show_sql=true
2. Create a new custom field for Layout
3. Add some value to new custom field at any existing page
4. Check that some sql are executed to expandoValue table
5. Edit and save properties of Layout again without doing any changes to custom field:
   • Wrong behavior: unnecessary sql selects are executed to ExpandoValue
   • Expected behavior: no unnecessary sql selects are executed to ExpandoValue
