Preliminary test case updates
Add rule for test beam'es
Test case cleanup
Minor test case rework
Calculation of term_spec size (initial and next) changed

There seem to be some problem with realloc (core dump)
so the calculation of the term_spec size needs to be
"corrected".
Add new messages
Uncommented test cases
Ensure of incorrect number of terms when scanning property groups

At the end of the mfs_load_property_groups function, the
final property group list and property groups list is
"terminated". A call to mfs_ensure_term_spec with (incorrect)
size 4 was made prior to this to ensure enough data was available.
The correct size was 6!
