test_acis_power_cmds test should be updated to skip on GRETA (or use a SKA/data file)

What is the failing test? I can't tell from the issue description.

[jeanconn]

I thought the test was called "get_globfiles"

[jeanconn]

Nevermind. I'll go run it again. I assume it is whatever test wants to use AUG0618.
