Override getRecordsWithNotBlankFieldValues for non-String fields (#90)

* Override getRecordsWithNotBlankFieldValues in fflib_SObjects2

The base fflib_SObjects implementation casts every value to String, which
throws a TypeException on Date/Datetime/Number/Lookup fields. This override
generalises the check to "any non-null value, and for Strings also non-blank"
so the helper works for every field type.

Rename method to getRecordsWithNonBlankFieldValues

* Update fflib_SObjects2Test.cls

Rename method to getRecordsWithNonBlankFieldValues
