tests/upgrade: tweak test function name
The previous function name (`upgradeFromPrevious`) dates from an earlier
iteration where I had initially a `fcos.upgrade.from-previous` and a
`fcos.upgrade.from-current`. Though I changed it later to just have one
test.  Rename the function to match the final name.
