Enable/fix default.lua test cases

[white238]

These were turned off when we were fixing the input file functionality but can/should be turned back on.

Lines 17 to 32 in 6357a07

The input file also seems to be fundamentally broken with this error (or the error is wrong):

[ERROR (/serac/src/drivers/serac.cpp:223)]
Solid order '1' and thermal order '2'' do not match.

Also the integration tests have a file globbing problem that needs to be solved to re-enable them (thanks @chapman39 for locating this):

The solid ordering is an issue that arose after updating the input files to handle functional. I remember discussing this with @jamiebramwell but don't remember exactly what the error is about.

In any case, I think it's best to either completely remove the default lua or replace its contents with another currently existing (and working) lua file.
