Fix --hash regression

[mattwalo32]

What I did
When I previously changed the hashing behavior in #11010, I neglected to consider the case where someone provides --hash=* to docker configure. My code assumed that a service name would always be passed in explicitly. This change uses all project service names in the absence of any provided name .

Related issue
Fixes #11145, thanks for pointing this out!

LTGM, tests ok with --hash=* or --hash=serviceA,serviceB
