"Count the number 0 as empty" doesn't hide boolean fields unless output text is "0"

Problem/Motivation

When rendering a boolean field in views, it is currently not possible to hide the unchecked/off/0 value if you are using any Output setting other than "1/0".

Under No Results behaviour, there is a "Count the number 0 as empty" but this seems to work off the output value rather than the raw value.

Steps to reproduce

1. Install the standard profile
2. Add 2 Articles, one published and one unpublished
3. Add a new Content view of Articles, remove the Published filter. Ensure the view style is Fields
4. Add the Published field, set the Formatter to Boolean and Output format to anything other than "1/0"
5. Under No Results behaviour tick "Hide if empty" and "Count the number 0 as empty"
6. Preview the view
7. Notice that both nodes published fields are displayed
8. Edit the field again and change the output format to "1/0"
9. Re-preview the view
10. Notice that the unpublished node's published field has disappeared.

Proposed resolution

When checking empty with this field setting, compare the raw values rather than the rendered output.
