Tom Barron 8c3abfdfb0 Tests: lower case all fake uuid constants
Midway through the valid uuid conversion project, we decided
to use upper-case fake constant uuids.  For backwards compatibility,
we put both upper-case and lower-case versions of each constant
in the fake_constants file, with the goal of returning and removing
the lower-case versions when their usages had been converted to
upper-case.

This commit converts the lower-case usages of the constants to
upper-case and removes the lower-case definitions from the
constants file.
