null should be valid in the "value" of a Filter in the builder when the field is a restricted picklist

[novusphere-cons]

Summary

When editing SOQL, the keyword null is a valid value in a where clause, such as "WHERE my_picklist_field__c != null", however the Builder does not allow the keyword to be entered in the "value" section of the form.

Steps To Reproduce:

1. Start a new query.
2. Select an object (from), and any number of fields into the result set.
3. Add a filter on a restricted picklist field, and type the word null in the "Value" input field.

Expected result

The word null should be allowed.

Actual result

The input field is highlighted with a red outline and the help text indicating which values are acceptable for the picklist is shown instead.

Additional information

WORKAROUND: It's possible to switch to the regular text editor to edit the query and switch back to the builder. The query will execute and the builder will correctly show the value.
