Make ml tests portable

[damccorm]

#36333 incidentally regressed ML tests because:

1. These tests previously couldn't run on Prism because of a trigger type. This unsupported capability was removed in [Prism] Support AfterProcessingTime triggers - part 2 #36333
2. These tests assumed they'd receive a value error, but portable pipelines raise RuntimeErrors always

This should fix the problem

Also added #36378 for future proofing

[shunping]

Thanks for fixing that. Any other breaking tests due to prism supporting processing time trigger?

[damccorm]

This is all I've seen so far

[lostluck]

This is the best kind of regression. :D
