James Nugent 052345abfe core: Fix empty multi-variable type ... Previously, interpolation of multi-variables was returning an empty variable if the resource count was 0. The empty variable was defined as TypeString, Value "". This means that empty resource counts fail type checking for interpolation functions which operate on lists. Instead, return an empty list if the count is 0. A context test tests this against further regression. Also add a regression test covering the case of a single count multi-variable. In order to make the context testing framework deal with this change it was necessary to special case empty lists in the test diff function. Fixes #7002		2016-06-12 14:00:16 +02:00
