It seems that this somehow got lost in the commit/rebase shuffle and wasn't caught by the tests that _did_ make it because they were all using just one file. As a result of this bug, locals would fail to work correctly in any configuration with more than one .tf file. Along with restoring the append/merge behavior, this also reworks some of the tests to exercise the multi-file case as better insurance against regressions of this sort in future. This fixes #15969.
