Missing quotation marks when filter value is the name of a property

[darianferrer]

Hi, I found a strange behavior when filtering with breeze, when using as filter value the name of a property of the filtering entity, does not surround the value with single quotation marks, the following url filter a field by LastName, wich it's a property, in the second url filtering by LastNam has the quotation marks
