templater: raise error for unknown func

Previously, if a template '{foo()}' was given, the buildfunc would not be able
to match it and hit a code path that would not return so it would error out
later in the templater stating that NoneType was not iterable. This patch makes
sure that a proper error is raised so that the user can be informed.

Tests have been updated.
